What is heat flux?
Heat flux or the thermal flux, sometimes also referred to as heat flux density, is the rate of heat energy that passes through a surface. Depending on the exact definition of heat flux, its unit can be expressed as either W/m2 or W.It is defined as HαΔT, where H is the heat transfer coefficient in W/m2 K, A is the active surface area in m2, ΔT is the temperature difference
How to Calculate One Dimensional Heat Flux?
One Dimensional Heat Flux calculator uses Heat Flux = -Thermal Conductivity of Fin/Wall Thickness*(Temperature of Wall 2-Temperature of Wall 1) to calculate the Heat Flux, One dimensional heat flux, We mean that temperature is a function of a single dimension or spatial coordinate. The basis of conduction heat transfer is Fourier's law. The symbol q is the heat flux, which is the heat per unit area. dT/dx is the thermal gradient in the direction of the flow. Heat Flux is denoted by q symbol.
How to calculate One Dimensional Heat Flux using this online calculator? To use this online calculator for One Dimensional Heat Flux, enter Thermal Conductivity of Fin (ko), Wall Thickness (t), Temperature of Wall 2 (Tw2) & Temperature of Wall 1 (Tw1) and hit the calculate button. Here is how the One Dimensional Heat Flux calculation can be explained with given input values -> 1.300128 = -10.18/0.13*(299-300).
