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.

TL;DR: In this paper, a coupled numerical method was proposed to simulate the combined cooling effect of the entire field, which combines transpiration and film cooling within separate porous matrixes, and validated by experimental data obtained at Ma = 4.2 in an arc-heated wind tunnel.

TL;DR: In this paper, a double layer combined cooling design is proposed, where an inner layer with discrete slots and an outer layer with homogeneous porous matrix is used to diffuse the coolant extensively.

TL;DR: In this article, a commercial superabsorbent polymer, SAP-50, was used to make swollen hydrogel, and then a thermogravimetric analysis test of the home-made hydrogels was conducted.

TL;DR: In this paper, the experimental investigation and theoretical analysis on the unstable performances of transpiration cooling with phase change was performed at four mainstream temperatures and four coolant injection ratios in the electric heating wind tunnel at University of Science and Technology of China.
