ceramic porcelain mugs cup
The convective heat transfer formula can clearly see, the main influence factors of convective heat transfer:
The convective heat transfer coefficient;
The temperature difference;
The heat transfer area;
In addition, as with heat conduction, and the heat transfer time. These four factors in any increase, convection heat transfer will increase. In the actual production, according to the specific circumstances, to change these factors, in order to achieve the purpose of strengthening or weakening the convective heat transfer. For example, the production practice of summing up "code fast firing" method, is the adoption of appropriate code, reduce the air resistance, so that the smoke flow speed, the convective heat transfer coefficient increased from two (from the convective heat transfer coefficient formula can be seen. Alpha on and velocity 0.8 time is proportional to the square of). In this way, can the enhancement of convective heat transfer, combustion, in order to speed up the speed, improve the quality of the product.
