Item Análisis térmico para el proceso de secado de fideo tipo Regin en la empresa Industrias Catedral S.A, para determinar su eficiencia(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2022-09) Goyes Guerrero, David Nicolás; Cabrera Anda, Santiago PaúlThe experimental work begins due to the need to have an updated energy study regarding the evaluation of thermal efficiency levels in the noodle drying process of tunnel 1 in the company Industrias Catedral S.A; based on the need to quantify the heat used in a typical drying chamber, as well as the most representative energy losses generated in the production of noodles. In the experimental process of calculating the thermal efficiency, it began with the identification of the thermophysical parameters of the raw material, as well as the evaluation of the standard noodle production. The data collection and measurements of normal operating temperatures of the radiator, temperature in the trays, air speed at the outlet of the fans, speed in air outlets, heat used for the drying of noodles, fundamental factors that intervene in the analysis of heat transfer and utilization within a static drying chamber of type trays. As a result, the supplied heat was analyzed in a type chamber, for region noodles, the regin noodles take advantage of 4,067Item Análisis térmico de un prototipo de cámara de secado estática por convección y radiación de 1000 W para uso semiindustrial(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-04) Criollo Camacho, William Rene; Cabrera Anda, Santiago PaúlThe present research work is focused on the temperature distributions inside the drying chamber with a radiation heat source that in this case four infrared lamps of 250 W each are used. In order to obtain these temperatures, experimental analyses are carried out in the prototype of the chamber and also with a modeling of the dryer simulations were obtained in the software, in a transient state with time intervals of 180, 240 and 688 seconds. The methodology proposed for the study was software simulation, first verifying the modeling of the chamber, then proceeding with the steps for data entry such as: parameters for the type of analysis, type of fluid (air), initial conditions, selection of materials, boundary conditions, amount of heat and radiating surfaces, also through calculations of the parameters of heat transfer inside the chamber by natural convection, forced and radiation, with their combinations reaching 771 W, also obtained the variation of stored energy for the air of 15.65 W. Applying energy balance, the losses by convection to the outside are determined, which reach 25 W. The combined results of the heat transfer methods help to calculate the efficiency of the chamber in vacuum (without load) and considering only the heating of the air inside gives us 6.4 percent. In the experimental and simulated time intervals analyzed, the temperature distributions in the middle and lower part of the chamber reach maximum values of 47 and 58.75 degrees Celsius, respectively.Item Diseño y construcción de un banco de pruebas de calentamiento de aire en ductos para el Laboratorio de Energía de la Carrera de Ingeniería Mecánica(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-01) Almeida Almeida, Jhonny Efraín; Cabrera Anda, Santiago PaúlIn this technical project, information has been collected on the types of heat exchangers, types of fans, measurement systems, construction materials, heat and temperature analysis, as well as structural stresses and deformations. Subsequently, the support structure, the air ducts and a heat generating coil were designed and built, with the use of analysis methods exposed in specialized books and others such as the selection of alternatives by weighted criteria, specialized software in static analysis and simulation of fluids. Then the measurement and control equipment was assembled with these to finally put into operation the test bench for heating air in ducts by means of steam The air heating system consists of a shell and tube heat exchanger. The steam will be generated by a 2 horsepower boiler steam boiler. To carry out the performance tests, the air temperatures at the outlet of the exchanger have been measured, controlling by means of a regulation damper the amount of mass of air that enters it, from 100 percent = 0.0669 kilograms per second, 75 percent = 0.0502 kilograms per second and 50 percent = 0.0334 kilograms per second, thus taking the temperature variations through two K-type thermocouples placed in the sections of the ducts. And under an analysis of results it was determined that when the incoming air mass is reduced, the air temperature at the outlet of the exchanger increases from 43.01 degrees Celsius, 50.31 degrees Celsius and 65.36 degrees Celsius respectively at the air mass inlet.Item Diseño y construcción de una turbina tesla para un banco de pruebas de comprobación de eficiencia en la Facultad de Ingeniería Civil y Mecánica(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2017) Cabrera Acosta, Santiago Fabricio; Escobar Luna, Luis EduardoThe present project starts from the need to continue developing different sources of renewable energy generation. For the development of the construction and design of the Tesla turbine was based on the quantitative analysis of the flow rate and angular velocity in the transmission axis to determine the dimensioning of its mechanical elements having as main source of research in scientific articles related to the Area of renewable energy, turbine construction, fluid mechanics and mechanical design. The execution of the prototype assembly was carried out in the first instance with the stator casting in nodular iron using the machining operations on lathe and grinding, in the following instance the cold cutting CNC of the disks in stainless steel AISI 304 was made creating the external diameter of the impeller, then drilled the fluid exhaust holes, similarly proceeded to the construction of the side covers, cutting the PMMA sheet in the CNC machine to later center the holes in the lathe so that in it rests the parts of the turbine, also used the lathe for the manufacture of the shaft in stainless steel AISI 304 and the bearings in aluminum, in addition installed a digital control system programmed in arduino, sensed by a flow meter of hall effect To view the amount of water entering the turbine. For the installation of the hydraulic circuit was used 1 in, ½ in, ¼ in, ¾ in pipes with their respective accessories simulating fluid movement with a 3/4 HP motor pump with negative suction type. In order to finish it was carried out the respective tests of operation that allowed the correction of dimensions and some mechanical elements, also was verified the number of revolutions, the inflow rate to the turbine Tesla to obtain its efficiency and the curves of behavior in which they intervene besides the pressure and voltage. The mechanical efficiency is indicated with a value of 14% with a speed of 215 rpm and a flow rate of 18.5 l / min, obtaining a voltage of 3 V in direct current.Item Diseño y construcción del prototipo de un sistema de propulsión por chorro de agua para la empresa Fuera de Borda, en la ciudad de Puyo en la provincia de Pastaza(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2017) Quispe Largo, Paúl Rodrigo; Arroba Arroba, César HernánThe objective of this project is to design and construct a prototype of a machine capable of pushing a boat that navigates in rivers, in places where the flow of the river prevents the use of outboard propeller thrust systems, for the Fuera de Borda Company. In order to achieve the objective, the water jet propulsion system for vessels was analyzed. For the design of the system components, mechanical design equations as well as fluid mechanics theory were used; the values of the inlet and outlet piping diameters were obtained as well as the pressure, flow and power head required by the Propeller pump axial flow. The prototype of the jet propulsion system is made of metal plate for the ducts, nozzle and diffuser, taking into account that it must be removable in addition to considering certain parameters of operation of the machine as a greater speed of the boat than with an Outboard propeller. The thrust force is generated by the pump with the flow rate and the output velocity of the fluid.
