Heat Transfer Coefficient Meaning. Heat transfer coefficient is a quantitative characteristic of convective heat transfer between a fluid medium a fluid and the surface wall flowed over by the fluid. Hēt tranzfər kōifishənt thermodynamics the amount of heat which passes through a unit area of a medium or system in a unit time when the temperature difference between the boundaries of the system is 1 degree.
Heat transfer coefficient ua value is used to calculate the convective heat transfer between the steam and the metal that surrounds it. Ie thermal power per unit area q dqda. The convective heat transfer coefficient is dependent upon the physical properties of the fluid and the physical situation.
The coefficient of heat transfer depends upon physical properties of fluid and physical situation in which convection occurs.
The convective heat transfer coefficient is not a property of. C specific heat capacity of the system and. It is mainly used for convection mode of heat transfer between fluid and a solid. The rate of heat transfer between a solid surface and a fluid per unit surface area per unit temperature difference.
