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

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

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

HEAT TRANSFER FROM EXTENDED SURFACES



OVER VIEW OF HEAT TRANSFER
Heat transfer can be defined as the process by which energy transport takes place. When two physical bodies (object or fluid) are at different temperatures than transfer of thermal energy is known as Heat Transfer.

This occurs in such a way that the body and the surroundings reach thermal equilibrium. Thus, heat always flows spontaneously from a hot material to a cold one. It obeys 2nd Law of Ther ....etc

HEAT AND MASS TRANSFER


1. Define Heat transfer?
Heat transfer can be defined as the transmission of energy from one region to another region to
temperature difference.

2. What are the modes of heat transfer?
1. Conduction
2. Convection
3. Radiation

3. What is conduction?
Heat conduction is a mechanism of heat transfer from a region of high temperature to a region of
low temperature with in a medium (Solid, liquid or Gases) or diffe ....etc
