FREE FROST HEAT EXCAHANGER
ABSTRACT
A new concept has emerged in the field of zero - emission vehicles : the cryogenic automobile . The cryogenic automobile uses nitrogen , stored in liquid state , as its working fluid . The liquid nitrogen is pressurized , then vaporized in an economizer through which the exhaust from the expander runs in counter flow . The resulting gaseous nitrogen is superheated in an ambient temperature gas which is injected into a quasi “ isothermal expander to produce t ....etc

Building an economical and competent resource for energy storage, plays a key role in energy conservation as it can cut down the time radically, for both energy supply and energy demand. This innovative concept as crucial as locating fresh sources of energy, can actually enhance the output of the whole energy system there by escalating its consistency.

In phase change materials (PCMâ„¢s) like the salt hydrates, paraffinâ„¢s, non-paraffinâ„¢s and eutectics of inorganic, the storage of solar heat energy, leads to compactness and de ....etc

Robert Frost

Robert Frost (1874-1963) was one of the major American poets of the 20th century.
Frost was born on March 26, 1874, in San Francisco and educated at Dartmouth College and Harvard University. In 1885 his father died, and his mother moved with the family to Lawrence, Massachusetts. After graduation from high school, Frost sporadically attended college and earned his living by working variously as a bobbin boy in a wool mil ....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

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
