Modelling and design of a GaN based motor drive for the Nuna solar car

In recent years, electrical vehicle (EV) starts showing its unique advantages that the conventional combustion vehicles do not have. Together with the increasing interests on EV, the motor drive with higher efficiency and lighter weight also becomes more attractive. To reduce the time and cost for the development, the project is aiming for the...

Experiments and computations on unsteady separating flow in an expanding flume

An unsteady, separating flow with a free surface was investigated with a physical model and a numerical model. To simulate tidal flow, the prescribed flow rate at the inflow boundary was a half-period sine function of time. Measurements of velocities and wave heights were conducted by using LDV and a wave-height meter in a straight open channel...
