Heat exchangers are integral to numerous engineering systems such as power plants and process plants, facilitating the transfer of heat from high-temperature to low-temperature zones. They operate in configurations where both zones can be either separated or in direct contact, with shell and tube heat exchangers being among the most widely used designs.Course Content: Gain insight into the basics of heat exchangers, their various types, heat transfer mechanisms, temperature variations, and methods for calculating key parameters based on provided data.CAD Modeling in SpaceClaim: Learn to create detailed CAD models of shell and tube heat exchanger designs using SpaceClaim, starting with fundamental configurations and gradually incorporating components like baffles, tubes, tube bundles, tube plates, and shells.Mesh Generation with ANSYS Meshing: Master the process of generating high-quality meshes for different heat exchanger designs using ANSYS Meshing, focusing on techniques for boundary layer meshing to accurately simulate flow dynamics and heat transfer.Fluent Simulation Setup: Import meshes into Fluent via the Workbench interface to set up and execute comprehensive CFD simulations. Configure turbulence models, energy equations, material properties (e.g., water, copper), and boundary conditions for precise analysis.Solver Optimization: Explore methods to optimize solver settings, initialize solutions effectively, and accelerate convergence using advanced strategies.Results Analysis: Analyze simulation results such as pressure, temperature, and velocity contours to evaluate performance across different designs. Compare outlet temperatures and validate findings against analytical predictions using CFD-Post.Software Requirements: Install ANSYS 2022 R1 or ANSYS Student Version (with a 512 K cell limit) to participate in the course.Practical Project: Apply acquired knowledge through a practical project aimed at integrating and applying course concepts in a real-world engineering scenario.
