Thermal Applications

Principles of heat transfer, steady state of heat flow, conduction through compound media-series and parallel-conductivity of rubber tube and powder materials - heat transfer through fenestrations, thermal insulation and its benefits heat gain and heat loss estimation factors affecting the thermal performance of buildings, thermal measurements, thermal comfort, indices of thermal comfort, climate and design of solar radiation, shading devices central heating.

Introduction

The study of thermal applications is important because of its applications in various fields of engineering.

• Mechanical Engineering

In designs of internal and external combustion engines, refrigeration and air-conditioning plants, heat-exchangers, coolers, condensers, furnaces, preheaters, etc.

• Electrical Engineering

In designing cooling system for motors, transformers and generators.

• Civil Engineering

Control of heat transfer in dams, structures, buildings and tunnels.

• Chemical Engineering

The application of heat transfer is in freezing, boiling, evaporation and condensation processes.
