Numerical investigation on the characteristics of cavity-transpiration combined cooling for hypersonic vehicle leading edge

Dan Wang et al.

Summary: This paper proposes an optimization scheme of cavity-transpiration combined cooling for the wedge-shaped leading edge of hypersonic vehicles and investigates the effects of flight angle of attack, aspect ratio of the cavity and coolant injection mode using numerical simulations. The results show that the existence of the cavity reduces the lift-drag ratio of the leading edge, and the lift-drag ratio increases with the increase of the angle of attack. The temperature at the stagnation point is decreased by 94.78K and the cooling efficiency is increased by 9.8% by introducing a lip blunting structure.

Transpiration cooling of high pressure turbine vane with optimized porosity distribution

Wen Wang et al.

Summary: Additive manufacturing allows for the fabrication of porous structures with high mechanical strength for transpiration cooling of gas turbine blades. Most previous investigations on transpiration cooling have used flat plate geometry, but this study focuses on using the real geometry of a turbine blade. Numerical simulation and optimization are conducted on a transpiration cooled C3X vane with multiple porous zones. The results show that optimal designs should have large porosity at the leading edge and the downstream pressure side, forming an effective transpiration cooling film.

Investigation of full-scale porous injector plate transpiration cooling coupled with combustion in high-thrust H2/O2 rocket engines

Ping Jin et al.

Summary: This study investigates the cooling and thermal protection for future high-thrust H2/O2 rocket engines. A numerical model based on transpiration cooling is presented and validated by experiments. The results show that transpiration cooling with 13% of the total hydrogen mass flow rate can significantly reduce the gas side temperature of the injector plate and the thermal penetration depth. Increasing the coolant mass flow rate and decreasing the coolant inlet temperature can further improve the cooling effectiveness, and reducing the thermal conductivity of the porous media can lower the plate temperature.

Near-wall vortices and thermal simulation of coupled-domain transpiration cooling by a recursive regularized lattice Boltzmann method

Zhihui Zhang et al.

Summary: This study uses a recursive regularized thermal lattice Boltzmann method (RR-TLBM) to investigate near-wall vortices and the effects of flow states in a coupled-domain transpiration cooling system. The results show that near-wall flow structures exhibit spatial characteristics in the streamwise direction, and vortex evolution promotes downstream heat dissipation. The study also found that small-scale structures are beneficial for turbulent heat transfer. The cooling performance of the coolant film improves at lower Reynolds numbers but is impaired at higher Reynolds numbers.

Flow structure and heat transfer of transpiration cooling by using a LBM: The effects of wall blowing and spatially nonuniform injection

Zhihui Zhang et al.

Summary: Through numerical simulations, it is found that in transpiration cooling, the stable development and coverage of the coolant layer are crucial factors for flow and heat transfer. The influence of factors such as wall bowing and nonuniform injection on near-wall flow structures and heat transfer characteristics is also highlighted.
