Heat transfer from the Human Body
Why?
 It is a common experience to feel “chilly” in winter and “warm” in summer in our homes even when the thermostat setting is kept same.
Problem
Consider a person standing in a room maintained at 220C at all times. The inner surfaces of the walls, floors and ceiling of the house are at 10oc in winter and 25oC in summer. (Aperson = 1.4m2, Tperson = 300C, εskin = 0.95)
Qrad,winter = εσAs(Ts4 � ....etc

Abstract

A response surface model of the luminous flame emissivity of sodium pool fire has been proposed for use in safety analysis computer codes of a liquid metal fast reactor. The liquid sodium burns in air resulting in not only heat generation but also release of sodium oxide aerosols of sub-micron diameters. Aerosols levitating in air are radiative and they influence the allocation of combustion heat from the flame to atmospheric gas or sodium pool. The emissivity of the flame needs to be quantified, as it is one of user-specified param ....etc

NANOFLUIDS FOR HIGH PERFORMANCE COOLING SYSTEM
ABSTRACT
Downscaling or miniaturization has been a recent major trend in modern science and technology. Engineers now fabricate microscale devices such as micro channel heat exchangers, and micro pumps that are the size of dust specks. Further major advances would be obtained if the coolant flowing in the micro channels were to contain nanoscale particles to enhance heat transfer. Nanofluid technology will thus be an emerging and exciting technology of the 21stcentury. This paper gives a brief ....etc

Jet impingement heat transfer – Part I: Mean and root-mean-square heat transfer and velocity distributions
Abstract
Impinging jets provide a means of achieving high heat transfer coefficients both locally and on an area averaged basis. The currentwork forms the first stage of a two part investigation of heat transfer distributions from a heated flat surface subject to an impinging airjet for Reynolds numbers from 10,000 to 30,000 and non-dimensional surface to jet exit spacing, H/D, from 0.5 to 8. In the present paper,the rel ....etc
