Combined with the permeability and heat transfer properties of lamilloy configurations obtained by experiments

a one dimensional porous wall thermal heat transfer model was applied to the analysis of the mass flow rate

and the overall cooling effectiveness of different lamilloys according to the pressure drop between the two sides.The investigation of various effects on cooling effectiveness has been made

the results presented in this paper will be useful for the actual lamilloy design.At the same blow ratios

the double layer porous plate exhibits higher cooling effectiveness than single layer

but the difference of cooling effectiveness between the triple layer plate and the double layer plate is not significant.Compared with the traditional cooling scheme

lamilloy is a prospective cooling scheme for the gas turbine engines of next generation.
