Introduction

The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the Braun tube. It was a cold-cathode diode, a modification of theCrookes tube with a phosphor-coated screen.

A cathode ray tube is a vacuum tube which consists of one or more electron guns, possibly internal electrostatic deflection plates, and a phosphor target. In television sets and computer monitors, the entire front area of the tube is scanned repetitive ....etc

DESIGN AND FABRICATION OF PULSE TUBE REFRIGERATION SYSTEM

ABSTRACT
Cooling effect at one end of a hollow tube with a pulsating pressure in the inside gas, was first observed by Gifford and Longsworth in early sixties. This marks the inception of one of the most promising cryogenic refrigerators known as 'pulse tube refrigerator' (PTR). Cryogenics is the science of low temperature. Cryogenics refers to the entire phenomenon occurring below -150°C or 123K. Cryogenic engineering involves the design and development of ....etc

FAILURE ANALYSIS OF SHELL AND TUBE HEAT EXCHANGER
PROJECT REPORT
Submitted by
ALEX BABY ARUN M V JAIN RAJ .V VIJEESH VIJAYAN
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

Introduction

Thermal design of shell-and-tube heat exchangers (STHEs) is done by sophisticated computer software. However, a good understanding of the underlying principles of exchanger design is needed to use this software effectively.

This article explains the basics of exchanger thermal design, covering such topics as: STHE components; classification of STHEs according to construction and according to service; data needed for thermal design; tubeside design; shellside design, including tube layout, baffling, and shellside p ....etc

Rijke tube is an instrument which shows thermo acoustics phenomena: Rijke tube is simply a cylindrical tube with lot ends open and heat source placed in it. Thermo acoustics refers is the creation of sound in a device due to the transfer of energy from a thermal source to acoustic waves set up in the device.

The Rijke tube service an a convenient prototypical system for the study of thermo acoustics phenomena. The rounding of the tube is a result of stationary acoustic wave being setup in the tube. The rounding of the Rijke tube is a result ....etc
