Overview

Heat transfer is the flow of heat from one body to another or from one place to another. The three modes of heat transfer are conduction, convection, and radiation. Conduction takes place through direct particle contact without the particles leaving their positions. Convection occurs in fluids when

Key Concepts

Conduction is the mode of heat

Conduction is the mode of heat transfer in which the particles of the body do not leave their positions. In metals, free electrons carry heat quickly.

Convection is the mode of heat

Convection is the mode of heat transfer in which the particles of the fluid move. It occurs only in liquids and gases, not in solids.

Radiation is heat transfer in

Radiation is heat transfer in the form of electromagnetic waves from a hot body. It does not require any medium and travels with the speed of light in

An isothermal surface is a surface

An isothermal surface is a surface at every point of which the temperature is the same. It may be plane, spherical, or cylindrical. Heat flow is perpe

Temperature gradient is the rate

Temperature gradient is the rate of change of temperature with distance between two isothermal surfaces. It is a vector quantity with unit degree Cels

Learning Objectives

  • Understand the three modes of heat transfer: conduction, convection, and radiation.
  • Identify the conditions under which each mode occurs.
  • Define and use isothermal surface and temperature gradient.
  • Understand coefficient of thermal conductivity and thermal resistance.
  • Apply heat flow formulas for slabs in steady state.
