TL;DR: In this paper, the effects of thermal conductivity, porosity, and sphere diameter of the porous matrix on the temperature and saturation distributions within the matrix are studied, and a new model is based on the coupling of the TPMM with the local thermal non-equilibrium (LTNE), and used to describe the liquid coolant phase change and heat exchange processes.

TL;DR: Wang et al. as mentioned in this paper presented an experimental investigation on transpiration cooling of the wedge shaped nose cone with an unequal thickness porous wall using liquid water as coolant, and the experimental data indicated that the design of the unequal thickness walled nose cone is effective to solve the key issue of cooling stagnation point.

TL;DR: In this paper, a semi-attached rib-design for the ribbed channel is proposed, where the ribs are perforated at the rib corners to form two rectangular holes, so a portion of the fluid can pass through the holes.

TL;DR: In this article, an experimental investigation on transpiration cooling using water as coolant was conducted in the arc-heated wind tunnel of China Academy of Aerospace Aerodynamics (CAAA), with a free stream specific enthalpy, mass flow rate and Mach number of 2700kJ/kg, 645g/s and 4.2, respectively.

TL;DR: In this article, a series of new conservation equations for mass, momentum, and energy to describe the performances of fluid flow, heat absorption and phase change in porous matrix is presented.
