Abstract:
A complex physical and mathematical model of heat transfer in packets of flat cooled microdynamic gas-dynamic nozzles used for pumping gas-dynamic lasers is presented. A feature of such rocket nozzles is their small size ($\sim$15mm), so they quickly heat up, and therefore, an intensive heat sink is needed. The complex physical and mathematical model of heat and gas dynamics, heating and cooling is new, since all physical processes are interfaced at the boundary of a multiply connected region. The solution of the problem of cooling high-temperature gas-dynamic lasers is one of the main challenges in their design. The results of a numerical solution are obtained for gas temperatures, heat transfer coefficient, cooler temperatures, and also for temperatures in the critical section of the nozzle.
