Effects of heat-transfer rate and coolant flow parameters on heating and cooling rates
Journal of Engineering Physics, 1974It is shown that change in the heat-transfer coefficient over a wide range does not alter the heating or cooling rate, which is determined by the heat transfer along the flow.

Decline of nucleation in the heating process with a high heating rate
Chinese Physics B, 2014The effect of the heating rate on the nucleation of metallic glass in a rapid heating process starting from the glass transition temperature is investigated. The critical nucleus radius increases with the increase of the temperature of the undercooling liquid. If the increment rate of the critical nucleus radius, owing to the heating process, is higher

Cool! Rates of Heating and Cooling
Journal of Chemical Education, 2007In this Activity, students measure and graph the rate of warming for a chilled thermometer bulb held in room temperature air, for a chilled bulb held between two fingers, and for a few milliliters of chilled water. Students are familiar with the everyday phenomena of warming, but measurement affords the unexpected result that the process is not linear.

Heat-transfer rate in the condenser section of a heat pipe
Journal of Engineering Physics, 1973A dimensionless equation for calculation of the heat-transfer rate in the condenser of a heat pipe is derived on the basis of dimensional analyses of the fundamental convective heat-transfer equations. The experimental results are generalized.

Heating Rates for a Beat Frequency Laser Heated Plasma
Canadian Journal of Physics, 1975The heating of magnetized plasmas through the utilization of a beat frequency harmonic which is excited at a frequency near to that of a Langmuir mode in the plasma is examined. Heating rates are obtained for plasmas with temperatures in the range 1 eV to 10 000 eV. In addition, the effects of the plasma density and the mixing angle of the laser beams

Fire and Materials, 1980
AbstractIn this paper the definition of heat release rate in fires is given in terms of heat of combustion and mass loss rate of the fuel. Various components of the heat of combustion are defined. The dependency of heat of combustion components and mass loss rate on factors such as fire stages, oxygen to fuel ratio, heat flux received by the fuel ...

An overview of heat release rates (HRRs) for different vehicles driving through tunnels is presented. The focus is on understanding fire development and the influences of tunnel conditions on the HRR. The HRR describes the fire development in the form of energy release given in megawatts (MW) over a given time period.

Fire Technology, 1996
A simple, theoretically sound method for eliminating the effects of internal heat absorption on rate of heat release is described for the Ohio State University (OSU) Release Rate apparatus. By monitoring the temperature of metal walls and calculating the heat loss to surroundings caused by changes in wall temperature due to heat absorption, a complete ...

Anomalous Surface Heating Rates
Journal of Applied Physics, 1966Metals, semiconductors, and insulators, when exposed to the high irradiance produced by an arc image furnace, appear hot much sooner than predicted by heat theory. For an irradiance of 1500 W/cm2, the surface of the samples tested reached a temperature of 2000°K or more in a few milliseconds whereas the mathematical theory of heat conduction suggests ...
