An interaction integral method for calculating heat flux intensity factor with the XFEM
International Journal of Thermal Sciences, 2019Abstract The JT integral is defined to extract the heat flux intensity factor (HFIF), which is used to describe the singularity of heat flux near the tip of a crack, and the path-independence of the JT integral is theoretically proven. Based on the JT integral, the relationship between the HFIF and an interaction integral is established through ...

Waves on the surface of a vapor film under conditions of intensive heat fluxes
Physical Review E, 2008We investigate surface waves on the interface between a thin vapor film and a layer of liquid in the presence of a high steady heat flux. This problem arises when a metal surface heated to a high temperature is immersed into a cold liquid. The general boundary conditions, which take into account the temperature dependence of saturation pressure on the ...

A radiometer for measuring high-intensity heat flux density and a method of calibrating it
Measurement Techniques, 2012The construction of an instrument for measuring time-varying high-intensity heat fluxes with a density of up to 50 kW/m3 is described and a model of an absolutely black body for calibrating it is presented. The procedure for making the calibration is described.

An ignition model is developed for quasi-homogeneous propellants consisting of two perfectly mixed compnents which decompose independently in the condensed phase and then react in the gas phase. The model describes the heat propagation in the condensed and gas phases as well as the diffusion of components in the gas phase. The transition processes from

Theoretical prediction of solar heat flux intensity on parabolic trough collector systems
Materials Today: Proceedings, 2020Abstract Wide spread utilization of solar energy can be reduce a significant portion of the conventional energy for the benefits of nation economy. The solar water heating systems are one of the popular devices to harness the sun radiation incident on the surface of earth at free of cost.

Explosive collapse of vapor film under conditions of intensive heat fluxes
High Temperature, 2007The stability is investigated (linear and nonlinear analysis) of the interface between a thin vapor film and a layer of liquid in the presence of a steady heat flux from a metal surface heated to a high temperature to the vapor film and then from vapor to subcooled liquid.

Abstract The existence of extensive precipitating anvil clouds in intense tropical convection suggests that vertical air motions associated with the anvil clouds play a significant role in the mass and heat budgets of these systems. This paper uses three different sets of assumptions about the water budget of an idealized mesoscale convective system to
