In CFD (Computational Fluid Dynamics) verification of vehicle aerodynamics, detailed velocity measurements are required. The conventional 2D-PIV (Two Dimensional Particle Image Velocimetry) needs at least twice the number of operations to measure the three components of velocity ( u,v,w ), thus it is difficult to set up precise measurement positions. Furthermore, there are some areas where measurements are rendered impossible due to the relative position of the object and the optical system. That is why the acquisition of detailed velocity data around a vehicle has not yet been attained. In this study, a detailed velocity measurement was conducted using a 3D-PIV measurement system. The measurement target was a quarter scale SAE standard vehicle model. The wind tunnel system which was also designed for a quarter scale car model was utilized. It consisted of a moving belt and a boundary suction system.

Numerical experiment of Mg2Ni combustion synthesis was carried out by an experimentally validated, total mathematical model, in which effect of preheating of metals on reaction temperature, reaction time, conversion and reaction mechanism was assessed. The calculated data gave transient fields of temperature and conversion within a sample at various preheating temperatures. The results showed that the preheating of metals offers benefit in increasing maximum temperature, shortening a processing time, enhancing purification of a product and dominating solid combustion mode without liquid phase generation.
