An instrument to measure the convective heat transfer coefficient on large vessels

2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008
Hepatocellular carcinoma is one of the most common malignancies worldwide. During radiofrequency hepatic ablation, the tumor is heated by means of radiofrequency energy. The heating causes necrosis of the malignant tumor. Thus, if the procedure is successful it can cure the patient.

Dependency of thermal spreading resistance on convective heat transfer coefficient

Microelectronics Reliability, 2008
Abstract This paper presents a study of the thermal spreading resistance R th of a small heat source on a conductive substrate subject to bottom-side convective cooling. This problem has been investigated for a very long time and is well covered in the literature.

Intercomparisons of Experimental Convective Heat Transfer Coefficients and Mass Transfer Coefficients of Urban Surfaces

Boundary-Layer Meteorology, 2005
The convective heat transfer coefficient (CHTC) of an urban canopy is a crucial parameter for estimating the turbulent heat flux in an urban area. We compared recent experimental research on the CHTC and the mass transfer coefficient (MTC) of urban surfaces in the field and in wind tunnels. Our findings are summarised as follows.

Establishing non-linear convective heat transfer coefficient

Coupled Systems Mechanics, 2022
The 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.

Measurements of heat transfer coefficients within convection ovens

Journal of Food Engineering, 2006
Abstract 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.

The determination of convective heat transfer coefficient during frying

Journal of Food Engineering, 1999
Abstract The convective heat transfer coefficient during deep-fat frying was determined at different temperatures. In this study, aluminum wool filled with potato mash having a size of 0.05 × 0.05 × 0.003 m 3 was used as a model sample. Frying was performed by fixing the sample vertically to make the system symmetrical.

DETERMINATION OF THE HEAT TRANSFER COEFFICIENT DURING CONVECTION HEAT TRANSFER

Power Engineering Problems
The article is devoted to determining the heat transfer coefficient during convective heat transfer. Convective heat transfer or heat transfer is the process of heat transfer between the surface of a solid and the surrounding medium (gas or liquid). In this case, heat transfer occurs due to the combined action of thermal conductivity and convection ...

Time series estimation of convective heat transfer coefficients

Building and Environment, 1994
Abstract In this work a novel methodology for the estimation of convective heat transfer coefficients is presented. The convective heat transfer coefficients are estimated using novel and existing time series methods, and are compared with those obtained from the standard ‘ratio of means’ approach, and those given in the CIBSE Guide.

Determination of convective heat transfer coefficients in turning

1997
A Control Volume Finite Difference (CVFD) code which finds the heat transfer coefficients resulting in a calculated thermal field that matches the thermal field obtained in experiments, was developed. The code is capable of solving unsteady conduction. and convection-diffusion problems in two or three dimensions using cylindrical coordinates.

Decoupling Convective and Conductive Heat Transfer Using the Adiabatic Heat Transfer Coefficient

Journal of Electronic Packaging, 1994
In many heat transfer situations, such as those found in the electronics cooling field, more than a single mode of heat transfer occurs. For example, modules on a printed circuit board dissipate heat through convection to the air, through conduction to the board and through radiation to the surroundings.
