Numerical Analysis of Heat Transfer Performance of a Temperature Sensing Packet with Built in Conducting Rod |
| |
| Abstract: | With SIMPLEC method, the heat transfer and the few of a medium in a temperature sensing packet is investigated numerically, and the liquid solid coupling of natural convection in an enclosed cavity formed by concentric cylinders of different heights, seldom studied elsewhere, is dealt with. The effect of the ratios of diameters and heights of the cylinders on the heat transfer and the medium flow in the cavity as well as on the dynamic response of the valves are discussed. Some criteria for the design optimization of the temperature sensing packet are proposed. |
