My friend and I got into a discussion at the EcoMarathon about low speed aerodynamics. We know that the airflow changes at lower speeds, but we don't really know how.
Most of the
prototype cars there are more or less teardrop shaped tadpole trikes, like what you would design for a highway-speed car. He thinks that you could basically build a delta trike with a conical body that was chopped off at the back. Is this the ideal design? What is the ideal aero shape for low speed vehicles?
There doesn't seem to be much info out there about this stuff. Hopefully someone will have an idea!
Thanks in advance!
