This study commences by performing an experimental investigation to measure the temperature distribution within a casting system comprising a cylindrical aluminum casting and a green-sand mold. The experimental temperature measurements are then used to compute the effective heat transfer coefficient at the ...
The 6061 aluminum alloy cooling rate curves and surface heat transfer coefficient variation with temperature under different cooling methods was studied through using cooling curves which were obtained by end-quench,combine with finite difference method and inverse heat conduction method.The results show ...
The effect of tube diameter on the air-side performance is significant. Larger tube diameter not only gives rise to lower heat transfer coefficient but ... A Nuntaphan,T Kiatsiriroat,CC Wang - 《Applied Thermal Engineering》 被引量: 43发表: 2005年 Experiments on the Dehumidification Performance...
