As a continuous effort to develop a realistic mist impingement cooling scheme, this paper focuses on simulating mist impingement cooling under typical gas turbine operating conditions of high temperature and pressure in a simplified model of transform piece (double chamber model). Based on the heat-mass transfer analogy, the results of mist cases compare with the none droplet case could be enhanced 320% (the maximum enhancement of adiabatic cooling effectiveness) cooling effectiveness and reduce 108 K of wall temperature.

In this paper, oscillatory properties of solutions for neutral type nonlinear impulsive hyperbolic partial differential equations with several delays are investigated and a series of sufficient conditions for oscillation of the equations are established.
