Heat release rate calorimetry

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 ...

Heat flux measurements in the OSU rate of heat release apparatus

Fire Safety Journal, 2002
Thermal capacitance (slug) calorimeters were used to measure radiant and flame heat fluxes and the overall heat transfer coefficient at the sample surface in the Ohio State University (OSU) Rate of Heat Release Apparatus specified in FAR 25.853(a-1). The copper plate calorimeters gave radiant heat flux readings which were within 2% of a NIST calibrated,

Heat Release Regressions for GDI Engines

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">This paper presents heat release regressions for the combustion modes in a gasoline direct injected (GDI) engines. These heat release regressions can be used in one-dimensional flow codes and mean value models as a simplified representation of combustion.

Furnaces, Fuels and Heat Release

2012
Furnaces firing a variety of fuels have been used for steam production since the beginning of the industrial era (around 1823 or so). Over the years since, they have developed in size and sophistication to the highly efficient equipment now in operation for power generation, district heating and process steam production.

Basal forebrain heating and ADH release in dogs

Experientia, 1973
On a examine des effets d'un elevement local de la temperature du prosencephale basal sur le taux de l'ADH plasmatique et les reponses thermoregulatrices chez les chiens chroniquement munis de thermodes. On a constate en avant de la commissure anterieure une elevation de la concentration de l'ADH dans le plasma sanguin et dans la plupart des cas une ...

The effects of heat-release wall properties on boiling heat transfer

Journal of Engineering Thermophysics, 2007
It follows from an analysis of existing data that the parameters of boiling heat transfer essentially depend on the thermophysical properties and geometrical characteristics (roughness and thickness) of the heat-release wall. However, it has been impossible, so far, to fully and correctly evaluate the effects of roughness and thickness of the heat ...

Heat transfer and Reynolds' analogy in a turbulent flow with heat release

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1958
Es wird die Warmeubertragung von und zu einer voll entwickelten, warmeabgebenden, turbulenten Stromung in einem Rohr analysiert. Durch die Anwendung der Laplace-Transformation wird die partielle Randwertaufgabe der Temperaturverteilung in einem Rohr von kreisformigem Querschnitt auf eine gewohnliche Sturm-Liouvillesche Randwertaufgabe zuruckgefuhrt ...

Intensification of Turbulence by Chemical Heat Release

The Physics of Fluids, 1964
Volumetric chemical energy release is studied as a mechanism for enhancing the isotropic turbulent motion of a compressible fluid medium. Both the vortical and dilatational components are examined to determine the influence of irreversible heat addition from exothermic reactions.
