Usually BAF charges are determined by Carrier Conferences to be applicable for a certain period on a certain trade route. These Carrier Conferences are seen as a cartel for fixing prices.
Heat transfer. Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.
Definition of conduction. 1) the result of collisions between molecules; when one end of an object is heated, the molecules vibrate faster and the energy is transferred to their neighbors. 2) 1. Thermal conduction the transfer of heat between two solid materials that are physically touching each other. 2.
