We needed to optimize the angle of inclination of the radiators to balance the air flow through the core and the resultant drag. Lacking the inf rastructure to test the system in a real-world scenario, we turned to simulation, which enabled us to assess the flow rate and drag at different inclination angles in our radiators. Another challenge that we faced was uneven air flow within our accumulator leading to creation of local “hot” spots. We needed a tool to visualize the air flow inside the accumulator to diagnose the problem.
Ansys was an indispensible tool that made winning the Engineering Design event at Formula Student 2020 possible while developing us into industry-ready engineers. With the use of Ansys Fluent, our team reduced the overall size and weight of our radiators by over 24 percent and reduce the cell temperature by 15 percent.
We’re here to answer your questions and look forward to speaking with you. A member of our Ansys sales team will contact you shortly.
