Sonic propane jet fire experiments were carried out in absence of wind, with visible flame length ranging between 2.2 and 8.1 m. The thermal radiation intensity increased with the mass flow rate and the flame length. The net heat released was also computed and a correlation for the flame length as a function of Q is proposed. The surface emissive power and the fraction of heat irradiated were e...

The goal of the inverse analysis is to find a set of heaters over some parts of boundary, called the heater surface, to satisfy the desired heat flux profile over the design surface. Micro-genetic algorithm is employed to inverse design of a radiant enclosure with absorbing-emitting medium. The direct problem of radiative heat transfer is solved by the discrete transfer method. The inverse prob...

Annealing furnaces are used to heat steel in order to change its chemical structure. In this paper we model an electric radiant furnace. One of the major defects in steel strips processed in such furnaces is a wave-like pattern near the edges of the strip, apparently due to extra heating near the edges. The aim of the paper is to model this effect and provide a way to calculate the elevated tem...

The current study involves developing a three-dimensional transient finite element (FE) model to evaluate the thermal performance of an attic radiant barrier system (ARBS) as an energy efficient technology. The heat transfer modes of convection, radiation, and conduction were considered in the FE model. The results from the FE analysis were then validated based on hourly experimental data colle...

Foraging time may be constrained by a suite of phenomena including weather, which can restrict a species' activity and energy intake. This is recognized as pivotal for many species whose distributions are known to correlate with climate, including kangaroos, although such impacts are rarely quantified. We explore how differences in shade seeking, a thermoregulatory behavior, of 2 closely-relate...

Heat flux gauges are one of the devices that are used to determine the heat loads to which high-speed aerospace structures are subjected during flight. Prior to installation, these gauges are calibrated. The calibration system must be well understood if the heat flux gauges are to provide useful data during flight tests. A pseudo three-dimensional model of the radiant heat flux gauge calibratio...

This paper reviews some of our recent applications of computational fluid dynamics (CFD) to model heat and mass transfer problems in neonatology and investigates the major heat and mass-transfer mechanisms taking place in medical devices, such as incubators, radiant warmers and oxygen hoods. It is shown that CFD simulations are very flexible tools that can take into account all modes of heat tr...

Hypothermia and postoperative shivering are uncomfortable and may be dangerous. This study demonstrates that postoperative shivering may be controlled quickly and effectively with radiant heat, thereby reducing oxygen consumption and increasing thermal comfort.
