Heat transfer is a discipline of thermal engineering that concerns the generation use conversion and exchange of thermal energy between physical systemsheat transfer is classified into various mechanisms such as thermal conduction thermal convection thermal radiation and transfer of energy by phase changesengineers also consider the transfer of mass of differing chemical species.

Conduction convection and radiation formula. Often conduction convection andor radiation take place together. Consequently the main modes of heat transfer in the stratosphere are radiation and conduction. The main difference between conduction convection and radiation is conduction is nothing but the heat transfer from the hotter part to the colder one.

2 combined conduction and convection we can now analyze problems in which both conduction and convection occur starting with a wall cooled by flowing fluid on each side. Convection is the heat transfer by up and down motion of the fluid. Thermal conduction and thermal convection seldom take place in isolation however.

Conduction convection and radiation. Radiation occurs when heat travels through empty space. As discussed a description of the convective heat transfer can be given explicitly as.

There are many mathematical formulas corresponding to physics and chemistry tending to explain these processes of heat transfer but the central thing is that they occur under three different procedures. However there is horizontal convection in the stratosphere known like advection which is a horizontal heat transfer due. Conduction convection radiation transfer of heat occurs through three different processes.

Conduction convection and radiation energy can be transferred by conduction convection and radiation. Conduction convection and radiation are the types of heat transfer. For heat transfer calculations involving convection conduction andor radiation combined its convenient to use thermal resistances for each type of heat transfer in calculations.

Heat transfer is defined as the process in which the molecules are moved from higher temperature region to lower temperature regions resulting in transfer of heat. Vertical convection does not occur in the stratosphere because in this layer of the atmosphere the gases move only horizontally.
