“…The Solid Oxide Fuel Cell (SOFC) for example could be used, mostly if species like hydrogen and light hydrocarbons are available onboard. In the meantime, liquid fuel (stored for propulsion application when burned in the combustion chamber) may encounter temperature that pyrolyses it and that produces light species [1][2][3][4][5] . Since the higher the H 2 or light hydrocarbons content, the longer the life time of the fuel cell, using heavy fuel would decrease the life time of the fuel cell.…”

“…Therefore, it is necessary to alleviate the cooling deterioration relating to this vapor block phenomenon by applying a new design of the transpiration cooling process. Zhao et al (2014) experimentally studied the transpiration cooling of a nose cone with unequal wall thickness. The experiment was conducted based on the arc heated supersonic free jet facility and liquid water was used as a coolant.…”

Non-uniform heating and vapor blockage deteriorate the effectiveness of transpiration cooling, and an optimization method by using porous media with a gradually-changed structure is proposed. The numerical tool based on a two-phase mixture model and local thermal non-equilibrium assumption considering variable properties of coolant is applied. Porous media with linearly-changed porosity or particle diameter is analyzed. The transient results presented that the structure of gradually-changed porosity (or particle diameter) with appropriate parameters can delay the heat transfer deterioration. And it is confirmed that the present theoretical model is an effective tool for optimization design of transpiration cooling system.

“…The coolant used and its specific capacity was the most influential parameter for the cooling efficiency. Zhao; Wang; Ma; Lin; Peng; Qu and Chen [23] presented a supersonic experimental investigation on transpiration cooling of a nose cone model with unequal thickness walled configuration using liquid water as coolant. Their experiments showed that ice cake appeared at the nose cone surface at main stream Mach number 2.0, stagnation pressure 174 kPa and mass flow rate 2.286 kg/s with an enthalpy 300 kJ/s.…”

The present study is focused on investigation of heat transfer from a porous plate by cooling of air and surface with transpiration cooling. Effects of Reynolds number of hot air (Re= 3035, 3200, 3300, 3580), effects of flow rate of water as a coolant (ṁwater= 0.000083, 0.000116, 0.000166, 0.000249 kg/s) on local wall temperature and cooling efficiency of porous flat and the system inside a rectangular channel with air as a hot gas stream and water as a coolant were investigated numerically. In this study; different from the literature, transpiration cooling was used as a cooling mechanism of air. It was observed from the results that increasing Reynolds number causes an increase on surface temperature and a decrease on cooling efficiency of porous plate and system. Increase of Reynolds number from Re=3035 to 9430 causes a decrease of efficiency of the system of 13.7%. Increasing water flow rate nine times causes not only a decrease on average surface temperature of 1.1% but also an increase of 6.5% on efficiency of porous plate and an increase of 19.1% on cooling efficiency of the system. Numerical results prepared by RNG k-ε turbulence model generally have a good approximation with experimental results.
