Characterizing heat release rate transients
Fire Safety Journal, 2012Abstract A series of experiments was performed to characterize the time response of a large-scale open calorimeter to square-wave pulses in terms of peak heat release rate, width of the peak, and conservation of energy. Quantitative heat release rate measurements of full-scale fires up to 2.7 MW were conducted using the principle of oxygen ...

Heat Release Rates of Burning Items in Fires
Journal of Propulsion and Power, 2000Heat release rates of typical items in fires are needed as a prerequisite for estimating fire growth and temperatures in structural fires. That is, these burning rates, in terms of heat release rate vs time, are required to be specified by the user as input to single-room and multiroom structural fire computer codes such as CFAST, FASTLite, FPETool ...

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 ...

Methods to characterize heat release rate data
Fire Safety Journal, 1990Methods to characterize experimentally measured heat release rate data are developed. Exponential and t-squared representations are considered in detail; algorithms for these two representations are presented. These characterizations require the selection of two representative data pairs from a measured heat release rate history and evaluation of the ...

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 ...

Probing boron thermite energy release at rapid heating rates
Combustion and Flame, 2021Abstract Boron (B) is a promising fuel for energetic materials due to its high gravimetric and volumetric energy density. The enhanced ignition and combustion of B in a thermite with CuO and Bi2O3 and their mixtures compared to single metal oxides was recently demonstrated.

Heat release rate in diffusion flames
Thermochimica Acta, 1996Abstract The dependence of heat release rate on fuel- and environment-based parameters is discussed. The parameters are the combustion efficiency and its convective and radiative components, net heat of complete combustion and heat of gasification, molecular weight of the gasified fuel, equivalence ratio, external and flame heat flux, and surface re ...
