The modern FGMs composite materials have a complex internal structure due to the fact that they consist of several different phases. In this paper, a sudden cooling process (thermal shock) at the upper side of FGM circular plates having discrete vari

This work discusses an application of a meshfree, semidiscrete finite element method to solving the ‘thermal shock’ problem for a thin, cylindrical plate made of functionally graded ceramics. The unsteady heat conduction equation is discretized i

The work focuses on the numerical study of FGM grading-pattern impact on the temperature distribution in the cylindrical plates made of Al2O3/ZrO2, under the thermal shock. Three patterns of material grading are studied, each composed of 9 layers wit

This paper focuses on the problem of temperature field and evaluation of the heat transfer coefficient in FGM cylindrical plates subjected to thermal shock. The cylindrical plates are made of five ceramic layers: purely Al2O3 layer and composite laye

This article describes a numerical model of the plate-fin air-to-air heat exchanger that can be used in simulations of gas dynamic systems. The model is based on unsteady one-dimensional compressible-flow equations for hot gas and on steady incompres
