Hi guys , im lakiya so today im doing a heat transfer today .
Heat transfer is a discipline of thermal engineering that concerns the generation , use , coversion, and exchange of thermal engergy between physical systems. Heat transfer is classified into various mechanisms , such as thermal conduction , thermal convection , thermal radition , and transfer of energy by pharse changes.
Next is , convection is single or multiphrase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid , most commonly density and gravity.
Radiation is energy that comes from a source and travels through space at the speed of light . The energy has an electric field and a mangentic feild associated with it and has wave-like properties you could also call radiation electromagnectic waves
Conduction: transfer heat from one object to another when they are in direct contact with one another
Heat is defined as the flow of energy from a warm to cooler object
