抄録
内容記述 Numerical solutions have been obtained for a steady viscous flow induced by a small boundary-layer blowing through three slots. The analysis is assumed to be two-dimensional, incompressible and also laminar. The analysis is made on the basis of the vorticity transport and energy equations in the conservation form, and the Poisson equation for the stream function. They are solved using the time-marching technique, together with the SOR method. The results show that a decrease in slot dia. and pitch and velocity ratio results in a reduction of the recirculating regions, but the present temperature field strongly is not affected by a recirculating flow near the blowing slots. A blowing fluid is strongly accelerated and heated by the cross flow at the leading edge of a plume. However, the stream-wise velocity component of the blowing fluid is almost constant along the plume. Moreover an increase in slot dia. or a decrease in slot pitch increases local Nusselt number and film cooling effectiveness on the slotted wall. It is also indicated that the calculated recirculating zones vary with numerical schemes used.
