Test Preparation

GATE preparation,  especially when the clock is ticking, requires great planning! 
Watch the overview lesson so that you will have a precise idea of which lessons are suited to your need.

Overview

Introduction to the working of heat exchanger,  types of flow, related technical terms.

Heat Exchanger Lingo

Parts of a shell and tube heat exchanger and the number of passes are explained with diagram.

Shell and Tube Heat Exchanger

How to derive overall heat transfer coefficient by finding total resistance;
 Fouling Factor,  what affects it, how it affects performance.

Total Resistance, Overall Heat Transfer Coefficient

Derivation of log mean temperature difference for co-current flow .

Log Mean Temperature Difference (LMTD)

Temperature profile of fluids in a heat exchanger flowing counter current to each other, cases of temperature crossings are discussed (important concept for GATE), LMTD when heat capacity rates are equal.

LMTD-2

Correction Factor, why use counter current flow? LMTD of condensers and boilers.

LMTD -3 : Correction Factor

What is the maximum temperature change a fluid can undergo? Which fluid will undergo that temperature change? Why do we focus on minimum heat capacity rate?
Get your concepts right!

Effectiveness : NTU method-1

Derivation of effectiveness of co_current double pipe heat exchanger is shown, the concept of transfer unit is explained and thus, is made  easier to imagine

Effectiveness:NTU method-2

M.Tech in Process Modeling and Simulation. Research scholar @ IIT BHU, and a teacher by heart, ranked 304 in Gate 2018, a badminton freak.

This course is all about the Heat Exchangers which is a device that is used for transfer of internal thermal energy between two or more fluids available at different temperatures. In most heat exchanger, the fluids are separated by a heat transfer surface and ideally they do not mix. So this course will cover up each and every minute details about the process and mechanical design of Heat Exchangers.

I am an M.Tech student of NIT TRICHY. I have done B.Tech in Chemical Engineering.GATE 2018 rank 704.
