Abstract: In this paper, a new proper orthogonal decomposition (POD) analysis method is proposed for numerical analysis of thermal mechanical engineering problems consisting of multiple media. After the creation of a heat conduction solution database for each medium, the “snapshot” approach of the POD technique is applied to facilitate reduced-order modeling (ROM) of the unsteady heat conduction behavior. The snapshot matrix is constructed medium by medium by collecting individual medium solutions at different instances in time through a columnwise manner. By means of expressing physical variables in terms of reduced modes at the individual medium level, a system of differential equations with respect to time is formed by utilizing the consistency conditions of the physical variables on interface boundaries. The solutions of the problem can be obtained by solving the system of equations at different time stops. Two numerical examples are given to demonstrate the efficiency of the proposed method.

TL;DR: In this paper, the effects of the surface-catalysis efficiency on aeroheating characteristics are studied using the Navier-Stokes solver with a cell-centered finite-volume scheme, including the finite-rate chemistry and two-temperature thermal nonequilibrium models.
Abstract: In this paper, effects of the surface-catalysis efficiency on aeroheating characteristics are studied. The Navier–Stokes solver with a cell-centered finite-volume scheme, including the finite-rate chemistry and two-temperature thermal nonequilibrium models, is implemented in this work. The ELECTRE flight trajectory at 53 km is used for validating the developed solver. Several cases with different catalytic recombination coefficients are studied to investigate the effects of catalysis efficiency under the condition of radiative equilibrium for the C series of Radio Attenuation Measurement project II flight trajectory at 71 km. It is revealed that distributions of heat flux and wall temperature have the similar tendency for all cases except for the Stewart model. Heat flux and wall temperature do not grow endlessly as the catalytic recombination coefficients are increased. It is the gradient of species density rather than gradient of temperature that leads to the significant differences of heat flux...
