  • In this paper, we propose a new technique for filling holes in triangular mesh. First, arbitrary shaped holes are detected. Second, source and target hole patches are generated through triangulation, refinement, fairing, and smoothing. Finally, the shape difference between the two patches is analyzed and a patch with enhanced features is obtained through blending between patches. The effectiveness of the proposed technique is demonstrated by applying the hole filling technique to the triangular mesh model with various shaped holes.

  • The objective of this research was to investigate the enhancement of heat transfer by wire mesh in impinging air jet system at the potential core region. The first experiment was carried out without mesh between nozzle exit and flat plate and the second experiment was done with mesh between them. When mesh was installed in front of the plate, heat transfer has been Increased due to the acceleration between rectangular halls and divided small jet In case clearances are changed, heat transfer comes to maximum under the condition of C=1mm, irrespective of nozzle exit velocity and H/B. Also the average heat transfer enhancement rate of a flat plate with mesh has been increased about 44% at maximum under the condition of U=18m/s, H/B=2 and C=1mm, compared to the result of a flat plate without mesh.

  • Research for climate control seats is being vigorously pursued because requests for passenger's thermal comfort are increasing. Recently, thermoelectric devices have been applied to automotive seats for both cooling and heating operations. The climate control seats using thermoelectric devices can rapidly control the air temperature passing through the devices and directly affect the thermal comfort of passengers. The performance characteristics of the climate control seats were analyzed by experiments for two different types of a leather covered seat and a mesh applied seat. Experimental results show that the cooling and heating performance for the mesh applied seat by using the discharge port of the shape of nozzle was improved significantly in comparison with that for the leather covered seat. The variation of temperature between the inlet air and the outlet air of the climate control seat for the enhanced mesh applied type was by $-3.5^{\circ}C$ at cooling mode, and was by $15.0^{\circ}C$ at heating mode, after about 30 minutes, respectively. Also, it is possible to provide rapid thermal comfort to passengers sitting on the seat in the vehicle cabin by using the proposed climate control seat.
