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 (k_{o}), Wall Thickness (t), Temperature of Wall 2 (T_{w2}) & Temperature of Wall 1 (T_{w1}) 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).
