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

ABSTRACT
Tar column recoiled E4509 in the phenol plant of HOCL found failed in service un like any other exchanger s in phenol manufacturing process .Each failure very high cost to HOCL in terms of production loss due to down time for maintence and due to the loss of therminol liquid to the process .the loss due to each failure found to be nearly RS 1.5 chore >the cost of tube bundle in SS-316 is ....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

COOLING OF HELMET WITH PHASE CHANGE MATERIAL


1. Introduction

Motorcycle helmets greatly reduce injuries and fatalities in motorcycle accidents. Thus, many countries have laws requiring standard helmets to be worn by motorcycle riders. Safety is a primary feature of a motorcycle helmet. Modern helmets are fabricated from plastics, often reinforced with Kevlar and carbon fiber. The helmet has two principal protective components: a thin, outer shell made of ac ....etc

SOLAR HEAT ENERGY STORAGE IN PHASE CHANGE MATERIALS
ABSTRACT
Developing efficient and inexpensive energy storage devices is as important as developing new sources of energy. Energy storage can reduce the time between energy supply and energy demand, thereby playing a vital role in energy conservation. It improves the energy systems by smoothening the output and thus increasing the reliability.
This paper deals with storage of solar thermal energy in materials undergoing phase changes. PCMs, which include salt hydrates, ....etc

ABSTRACT
MICRO-SCALE REGENERATIVE HEAT EXCHANGER
A micro-scale regenerative heat exchanger has been designed, optimized and fabricated for use in a micro-Stirling device. Novel design and fabrication techniques enabled the minimization of axial heat conduction losses and pressure drop, while maximizing thermal regenerative performance. The fabricated prototype is comprised of ten separate assembled layers of alternating metal-dielectric composite. Each layer is offset to minimize conduction losses and maximize heat transfer by boundary layer ....etc

Introduction

A device designed to transfer heat between two physically separated fluids; generally consists of a cylindrical shell with longitudinal tubes; one fluid flows on the inside, the other on the outside.

Any of several devices that transfer heat from a hot to a cold fluid. In many engineering applications, one fluid needs to be heated and another cooled, a requirement economically accomplished by a heat exchanger. In double-pipe exchange ....etc
