Investigation of the effect of electric field on the characteristics of heat transfer in a combustion chamber with a porous cooling flow train
Annotation
The effect of an external electric field on the characteristics of heat and mass transfer is investigated in a combustion chamber whose cooling flow train is filled with a porous material. It is found that, if a constant negative potential of $900$ V is applied to the combustion chamber, the heat flux from the combustion products to the firing wall increases (by a factor of $\sim2.7$), and in the case of a positive potential this heat flux decreases. The obtained experimental data are explained by the effect of ionic wind which interacts with the boundary layer of the firing wall to cause a variation in its geometric and thermophysical parameters, as well as leads to a change in the flame surface. The observed effect may be used to develop an effective system of cooling the combustors of power plants.
