Study of conjugate heat transfer in the nozzle grid of a gas-dynamic laser

The authors present experimental data for and construct a mathematical model depicting heat transfer and gas flow characteristics in the nozzle grid of a gas dynamic laser using a high-temperature vibrationally nonequilibrium gas mixture of carbon dioxide and nitrogen and water vapor. The mathematic...

Beschreibung
Zusammenfassung:	The authors present experimental data for and construct a mathematical model depicting heat transfer and gas flow characteristics in the nozzle grid of a gas dynamic laser using a high-temperature vibrationally nonequilibrium gas mixture of carbon dioxide and nitrogen and water vapor. The mathematical formulation incorporates subsonic as well as supersonic flow and also accounts for permeability and catalytic activity at the nozzle wall.
