The defrosting is very important in vehicle. In the paper, some improved proposals to the lack performance of the vehicle windshield defrosting would be discussed by using computational fluid dynamic (CFD) numerical simulation analysis and experiment to validate the improved proposal. The improved proposal including change the angle of the grill of wind outlet, and add grill on the left and right side. The discrepancy of the two methods is in 5%, which is acceptable. By the improved proposal that the windshield defrosting area is increased and also the requirements is satisfied.

Calculation of the resistance and trim of highspeed boat at planning regime is a complex hydrodynamic problem. At the planning regime, with the aid of lifting force, the boat is lifted over the water surface with high trim angle. Many methods have been applied to calculate the resistance and the trim of the high-speed boat at this planning regime. This paper will study the two typical methods, the first one is empirical method by Savitsky [1] and the second one is the computational fluid dynamic method (CFD). The calculation results of two methods are compared with experimental results.
