The full N-S equations were solved using Beam-Warming approximate factorization method and a high-order compact-difference scheme for the synthetic flow field of vectoring control of a primary jet with the adjacent synthetic jets.

2 performed experiments on the effectiveness of using synthetic jet actuators to perform vectoring control of primary flow.

6-meter high reinforced concrete chimney by using the directional controlled blasting technology.

This paper introduces a demolition method for tall tube shaped buildings such as chimneys and water towers by directional controlled blasting through a practical implementation, and the relative blasting parameters are put forwar

In this paper, it was stated that the orientation control technique of chimney demolition on the condition that chimney s center of gravity has shifted, and a valuable investigation in the technical measures of correct deviation by blasting was made.

According to the extensive use of the technology of the breaking coal by the water power and the action characteristics of drilling hole by the water power in coal seam, this paper puts forwards a new scheme of the orientation control of water power drilling.
