What is heat flux?

Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time. In SI its units are watts per square metre (W/m2). It has both a direction and a magnitude, and so it is a vector quantity.

How to Calculate Heat flux?

Heat flux calculator uses Heat flux=Thermal Conductivity*(Temperature/Length) to calculate the Heat flux, Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time. Heat flux and is denoted by q" symbol.

How to calculate Heat flux using this online calculator? To use this online calculator for Heat flux, enter Length (l), Temperature (T) and Thermal Conductivity (k) and hit the calculate button. Here is how the Heat flux calculation can be explained with given input values -> 283.3333 = 10*(85/3).

FAQ

What is Heat flux?

Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time and is represented as q"=k*(T/l) or Heat flux=Thermal Conductivity*(Temperature/Length). Length is the measurement or extent of something from end to end, Temperature is the degree or intensity of heat present in a substance or object and Thermal Conductivity is the rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance.

How to calculate Heat flux?

Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time is calculated using Heat flux=Thermal Conductivity*(Temperature/Length). To calculate Heat flux, you need Length (l), Temperature (T) and Thermal Conductivity (k). With our tool, you need to enter the respective value for Length, Temperature and Thermal Conductivity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Heat flux?

In this formula, Heat flux uses Length, Temperature and Thermal Conductivity. We can use 3 other way(s) to calculate the same, which is/are as follows -

Heat flux= -(Thermal Conductivity/Wall thickness)*(Temperature of wall 2-Temperature of wall 1)
Heat flux=Heat transfer coefficient*(Surface temperature-Temperature of characteristic fluid)
Heat flux=Heat transfer coefficient*(Surface temperature-Recovery temperature )
