Experimental investigation on condensation heat transfer in horizontal microfin and smooth tube with refrigerant R22;

Experimental study of frictional pressure drop characteristics of R410A-oil mixture flow boiling inside a small smooth tube was performed to promote the application of R410A in the compact heat exchanger of air-conditioner.

This paper introduces the clarifying influence of the intertube spacing, the tube arrangement,the heat flux and the working fluid on boiling heat tra(?)sfer of smooth tube bundles.

The article analyses and simulates optical systems with normal light sources,it also studies the characteristics of the usual optical components used in projection system like light pipe,micro lens array,etc.

Forecasting fouling characteristics of plain tube based on least squares-support vector machine for regression

The comparative experiments on the flow resistance and the composite fouling of the convergent-divergent tube and its corresponding plain tube were carried out.

According to the intensifying transmit heat theory,a double-pipe heat interchanger experiment system is designed,and light tube and corrugated tube with diameter 25 mm are chosen to do the experiment of the intensifying transmit heat function and fouling characteristics.

According to the intensify transmit heat theory,several kinds of the exchanger tube (light tube, whorl tube,ripple tube) is chosed to do the experiment of the intensify transmit heat function.
