: Heat exchanger is a device which is used for efficient heat transfer from one medium to another in order to carry and process energy. In this device, one medium is cooled while the other is heated. Generally all the heat exchangers have circular tubes with segmental baffles. Circular tube has less surface area contact than oval tube according to the fluid flow on it. Circular tube does not have aerodynamic configuration and increases total drag forces of fluid. In this project, design and analysis are done for oval tube heat exchanger with different orientation of oval tube to overcome these problems. So, we would like to modify the tube cross-section with elliptical profile for better heat exchange. It also increases the overall efficiency, heat transfer rate and smooth flow in the heat exchanger. The design of elliptical-tube is based upon the circular tube dimensions at equal fluid flow rate. These can be used in power plants as oil coolers with better performance. Modeling is done by using Catia-v5 or Solid-works-v18 and fluid flow and thermal analysis are carried out in Ansys-v15.0 software.
