Establishing non-linear convective heat transfer coefficient
Coupled Systems Mechanics, 2022The aim of the work presented in this paper is development of numerical model for prediction of temperature distribution in pavement according to the measured meteorological parameters, with introduction of non- linear heat transfer coefficient which is a function of temerature difference between the air and the pavement.

Convective heat transfer coefficient in compartment fires
Journal of Fire Sciences, 2013Heat transfer to compartment surfaces was measured in fully developed fire experiments. The experiments involved scaled compartments ranging from 1/8th to 3/8th with full-scale height of 2.54 m. Gas temperatures reached 1000°C, and total surface heat flux could reach 200 kW/m2, with convection accounting for 25% of the total.

Convective Heat Transfer Coefficients in Concentric Annuli
Heat Transfer Engineering, 2005Abstract The geometric shape of a passage's cross-section has an effect on its convective heat transfer capabilities. For concentric annuli, the diameter ratio of the annular space plays an important role. The purpose of this study was to determine to what extent research has been done on convective heat transfer in smooth concentric annuli and, if ...

Convective Heat Transfer Coefficient for Poultry Excreta
Transactions of the ASAE, 1978ABSTRACT DATA were analyzed to determine material and con-figuration specific constants for calculating the con-vective heat transfer coefficient for poultry excreta. The convective heat transfer coefficient equation used was: where hc is the heat transfer coefficient, G is the mass velocity, Dc is a characteristic dimension, and the con-stants are a ...

Sandwich holography for determining the convective heat transfer coefficient
Journal of Optics A: Pure and Applied Optics, 1999A sandwich hologram in the transmission mode is shown to be an efficient tool for determination of the heat transfer coefficient in a transparent fluid. The theory of the method, as well as its application to the free convection on a horizontal isothermal plate, is also given.

Measurements of heat transfer coefficients within convection ovens
Journal of Food Engineering, 2006Abstract Measurements of apparent heat transfer coefficients within a typical domestic fan oven and a commercial batch oven were performed using four different methods: back-calculation from transient temperature data; using heat flux sensors; from the mass-loss rate; a psychrometric method.

Evaluation of Reaeration by Convective Heat Transfer Coefficient
Journal of Environmental Engineering, 2018AbstractThe reaeration-rate coefficient (K2) is an essential parameter in water quality simulation because it aids predicting the water’s ability to assimilate organic pollutants.

Determination of Fluid-particle Convective Heat Transfer Coefficient
Transactions of the ASAE, 1995Fluid-to-particle convective heat transfer coefficient (hfp) was determined by continuous particle center temperature measurements in a hold tube by a temperature sensor system using the transmitter particle technique. The fluid used was carboxy methyl cellulose (CMC) at concentrations of 0.5, 1.0, and 1.2% (w/w). The carrier fluid temperatures were 22.
