Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
3.1. INTRODUCTION
Heat transfer is a subject that deals with the generation, use, conversion, and
exchange of thermal energy between a system and its surroundings. At the
molecular level, we can visualize thermal energy by the motion of particles and
quantify it by the overall kinetic energy of all the particles. Heat transfer can
then be explained as an exchange of the kinetic energy among particles via
collisions or interactions. In a gas, the particles move faster, on average, under
higher temperatures and transfer their kinetic energy to particles at lower
temperatures through collisions. In a solid, the particles vibrate faster under
higher temperatures and transfer their kinetic energy to particles at lower
temperatures through molecular interactions.
