An analysis is made on the cracks formed on the grinding mill cylinders and the fatigue failure is considered to be a main cause and also, the falling impact of some big blocks will somehow damage the grinding mill cylinders.

PIV experimental research on supersonic impinging jet;

Large eddy simulation of secondary eddy for impinging jet;

The study of vortex structure of impinging jet calculated using the swirling strength method;

Experimental research on roasting sweet potato with air-impingement technique;

Air-impingement is a new drying technology.

A creative conception was proposed to enhance heattransfer of grinding contactzone through jet impinging on the basisof analysis on the mechanism of burn during creep feed grinding,and an experimen- tal study was made on the characteristics of augmentation of heattransferwith jetimpinging.

A new method of enhancing heat transfer in grinding contact zone with jet impinging is presented on the basis of analysis on the mechanism of workpiece burn in creep feed grinding.

A creative conception is proposed to enhance heat transfer in grinding contact zone through jet impinging on the basis of analysis on the mechanism of burn during creep feed grinding, and a new apparatus of slotted & perforated electroplated CBN grinding wheel with radial jet is developed, the effect on heat transfer is studied through the experiment of intermitted creep feed grinding.

Experimental study of the effects of tabs on jet impingement heat transfer;

Experimental investigation on discharge coefficient of jet impingement holes within semi-confined channel

The thermal visualizations of jet impingement cooling with tabs are measured by using infrared camera to reveal the effects of tabs on convective heat transfer of impingement cooling.
