Non-Steady Flow Through a Heavily Loaded Actuator Disk

摘要

The present investigation is concerned with the non-steady axisymmetric flow of an inviscid, incompressible fluid through a heavily loaded actuator disk. Since the steady state problem is essentially non-linear, a closed form solution is not possible. The small perturbation theory is applied, and the first-order solution is obtained. The resulting perturbation equations which contain the steady state solution as coefficients are solved numerically by using the method of finite differences. The non-steady solutions are compared with the zeroth-order basic solutions. (Author)
