With the help of a CCD video camera and a wide-field stereo-microscope,the triple-phase contact line in a triangle-wetting region of a rectangular capillary microgroove is visualized.

In this paper,with high speed camera,the visualization experiments for the heat transfer characteristics of spray cooling on rectangle capillary microgroove groups surface were carried out.

An experimental investigation of the pressure drop of water in a horizontal rectangle micro-groove;

Theoretical analysis of axial dryout point height in vertical rectangular capillary microgrooves;

Dryout characteristics of evaporating liquid in vertical capillary microgrooves heat sink;

Using a wide field stereo-microscope,a high-speed camera and a CCD video camera,liquid dryout behaviors and axial wetting height in vertical rectangular capillary microgrooves were observed and measured under the conditions of pure evaporation and boiling heat transfer.

Under different boundary conditions, theoretical analysis is made for gas flow and heat transfer in micro rectangular channels where velocity-slip and temperature-jump prevail.

This article present the theoretical analysis of gas flow and heat transfer in micro rectangular channels in the regime of velocity slip and temperature jump.
