Course Overview

In this Lesson, modes of heat transfer are

explained. The basic concept of conduction, convection and radiation are there, you would be able

to understand the difference between conduction , convection and radiation through this lesson.

Modes of Heat Transfer

This lesson throws light on thermal conductivity, conduction in

gases, liquids and solids, Newton’s Law of cooling and a very important law i.e. fourier law of

conduction. All this has been explained in a very simple manner.

Conduction

Conduction of Heat Transfer Through a Slab

This lesson throws light on convection

thermal resistance, conduction-convention heat transfer through a composite slab, overall heat

transfer coefficient. The concept of overall heat transfer coefficient has been explained with the help

of numerical.

Overall Heat Transfer Coefficient

In this lesson, educator has taken the

different cases of conduction i.e. conduction heat transfer through a hollow cylinder, conduction

heat transfer through a composite cylinder. You can understand these concepts with the help of

Conventional Numerical in this lesson

Conduction Heat Transfer through a Cylinder

This lesson throws light on critical radius of

insulation, what is the physical significance of critical radius of insulation, formula has been derived

for critical radius of insulation for cylinder and sphere. The concept of critical radius of insulation has

been explained with the help of numerical.

Critical Radius of Insulation

In this lesson, educator has

explained the generalised conduction equation, detailed analysis of thermal diffusivity. Thermal

diffusivity is very important term in heat and mass transfer and educator has explained this in a very

simple manner.

Generalised Conduction Equation

This lesson throws light on

conduction with heat generation in a slab.

Conduction with Heat Generation in a Slab

In this lesson, educator has

explained the concepts on heat generation in a cylinder, generalised heat conduction equation in

cylindrical coordinate system, radial conduction heat transfer through a hollow sphere. These topics

are very important from examination point of view.

Conduction with Heat Generation in Cylinder and Sphere

This lesson throws light on fins, analysis of rectangular fins, different

cases have been taken like fin is infinitely long, fin is finite in length and tip is insulated, fin is finite in

length and looses heat.

Fins: Part 1

In this lesson, educator has explained fin efficiency , effectiveness of

fins and a numerical to understand the concept better.

Fins: Part 2

This lesson throws light on

transient conduction heat transfer, detailed derivation of time constant, lumped system analysis and

Biot Number. You can understand the concept with the help of Conventional Numerical in this

lesson

Unsteady or Transient Conduction Heat Transfer

In this lesson, Objective Questions

are solved. You can revise all the concepts taught in previous lessons with the help of these objective

questions. The questions are based on Conduction Heat Transfer. This lesson will help you gain

more proficiency on the theoretical concepts which were discussed earlier.

Objective Questions on Conduction

This lesson throws light on radiation, thermal radiation, electromagnetic wave spectrum, black body, etc

Radiation - Part (I)

In this lesson, spectral black body emissive power, variation of spectral black body emissive power, Stefan boltzmann law, wein's displacement law have been explained.

Radiation - PART - (II)

This lesson throws light on radiation properties, gray and diffuse surface, absorptivity, reflectivity and transmissivity and laws of reflection

Radiation Properties
