Rates of Heat Transfer - Physics

On previous pages of this lesson, we have learned that heat is a form of energy transfer from a high temperature location to a low temperature location. The three main methods of heat transfer - conduction, convection and radiation - were discussed in detail on the previous page.Now we will investigate the topic of the rate of heat transfer.

Effects of Using Fins and Carboceramics on the ...

Recent studies have shown that using the cooling fins is one of the most appropriate methods to eliminate the shrinkage porosities in the castings. In fact, Fins play the role of heat exchangers during the solidification and their usage is the same as that of chills. The cooling effect of fins is directly related to their geometry. Also the effect of fin on decreasing the time of local ...
