This report covers the steps and tests done to examine the daylight of our building model. We broke the process into five steps: constructing the model, daylight factor measurements, glare analysis, model improvement, and model simulations. Through these tasks, we were able to establish an understanding of daylight design as well as improve the base model layout that was originally provided. The model improvement and research provided us with a greater understanding of the positive effects of daylight as well as the importance of energy efficiency and sustainability. These insights gave our model importance by comparing it to real-world applications.

This report details the design of a spiral casing for a Francis turbine, a critical component in hydroelectric power generation. The primary function of the spiral casing is to ensure uniform fluid flow around the turbine runner. The design process involved calculating geometric parameters using SOLIDWORKS, a CAD software, followed by verification and optimization through simulations in ANSYS, a CAE software. Initial designs showed non-uniform pressure distributions and unwanted recirculations. By incorporating guide vanes and making iterative modifications, a more uniform velocity and pressure distribution was achieved. The final design demonstrated the effectiveness of using a fully spiral geometry for high head applications, and highlighted the need for iterative optimization and careful selection of vane profiles and angles to ensure efficient fluid dynamics. This work underscores the importance of computational tools in modern turbine design and provides a framework for further refinement in similar hydraulic applications.

The chassis frame is the structural backbone of a vehicle, primarily designed to safely carry the maximum load under all operating conditions. In two-wheelers, the chassis not only provides structural integrity but also sets the overall style of the vehicle. Commonly, steel is used for two-wheeler chassis due to its high density and strength, but alternative materials like aluminum alloys, titanium, carbon fiber, and magnesium are also considered to reduce weight while maintaining strength. This report focuses on the design and static analysis of a two-wheeler chassis frame. The modeling was performed using CATIA V5 software, and the structural analysis was conducted using ANSYS software. The study includes geometry characteristics, mesh generation, loading conditions, and result evaluation, specifically focusing on maximum principal stress and total deformation. The analysis was performed using an IGS file format for geometry import. The results indicate that the maximum stress occurs at joint locations, but all stress values are within the permissible yield limits of the materials tested. Consequently, the design is deemed safe. Stainless steel, being cost-effective and providing a satisfactory weight reduction, is identified as the most suitable material for the chassis frame.

The latest engineering equipment is increasingly focused on energy transitions that require the rapid transfer of heat. Consequently, there is a growing demand for heat transfer appliances that offer a low cost, a smaller size, and still deliver a high level of performance. It is essential to investigate the performance of these appliances or equipment, as well as the heat transfer rates of these appliances or equipment, in different thermal environments. In addition to the fact that these appliances are used in airplanes, spacecraft, vehicles, nuclear reactors, and many other places. With the use of heat exchangers, the heat energy is exchanged from the hot fluid to the cold fluid simultaneously at a maximum efficiency rate and the minimum operating costs. To design and do a prediction of the performance of a heat exchanger, it is necessary to be able to correlate the total heat transfer to the design parameters of the exchanger. These factors are the overall surface area, the temperature of the inlet and outlet fluid temperatures in the pipe, and the overall heat transfer coefficient of the pipe. During this project, the stress and thermal analysis of the heat exchanger pipe were performed. In this case, the temperature and heat distribution, rate of thermal conductivity, and properties of the steel materials were all taken into account in order to determine the temperatures and heat distribution. The materials required for designing and analyzing the performance of the heat exchanger pipe have been studied in detail. To reduce the thermal stress of the components, ANSYS has been used to model them and calculate the thermal stress. The thermal stress equation has also been developed. A thermal analysis was conducted on the pipes in the heat exchanger to reduce the thermal stress. In addition, the heat transfer rate and thermal conductivity of the model structure were evaluated. The observations of the deformation, maximum stress, and strain were made and in the end, a conclusion was reached.

Material handling in the manufacturing industry involves moving raw materials and products efficiently. Conveyor belts, crucial for this process, use motorized pulleys to facilitate the movement of materials, saving money, energy, and time. This study focuses on the design and analysis of a conveyor belt system used in almond drying. Key design parameters include required power, material load, and component selection for the belt, pulley, stand, and drive unit. Components are modeled in SolidWorks and analyzed in ANSYS for static analysis. The results ensure structural safety by evaluating deformation and stress under operational conditions. The study aims to create an efficient, economical conveyor system suitable for food processing industries, enhancing productivity and reducing costs.

This mini project presents a color sorting machine designed to sort objects into three categories based on their colors: red, blue, and others. Utilizing an Arduino microcontroller, a DC motor, relay switches, and a TCS3200 color sensor, the machine detects the color of each object as it passes through the sensor. If the object is red, the first crank mechanism is activated to sort it. If the object is blue, the second crank mechanism is triggered. Objects that are neither red nor blue are allowed to pass through to the end. This efficient and cost-effective solution demonstrates the practical application of color detection and sorting in small-scale automated systems.
