Temperature Management of the Internal Surface of Power-Plants Combustion Chamber using Semitransparent Materials

The paper examines control and management by temperature of the internal surface of combustion chamber walls for high performance diesel and turbine engines due to the application of semitransparent thermal barrier materials, coatings (determined by variable porosity) causing significant subsurface radiant overheating. The authors proposed a model for reducing NOx concentration due to a decrease of the surface temperature caused by a shift of radiant absorption zone to the depth of semitransparent thermal insulation.
