# Conductive Heat Transfer

Heat transfer by conduction

Thermal Elements

## Description

The Conductive Heat Transfer block represents a heat transfer by conduction between two layers of the same material. The transfer is governed by the Fourier law and is described with the following equation:

where

 Q Heat flow k Material thermal conductivity A Area normal to the heat flow direction D Distance between layers TA,TB Temperatures of the layers

Connections A and B are thermal conserving ports associated with material layers. The block positive direction is from port A to port B. This means that the heat flow is positive if it flows from A to B.

## Dialog Box and Parameters

Area

Area of heat transfer, normal to the heat flow direction. The default value is 0.0001 m^2.

Thickness

Thickness between layers. The default value is 0.1 m.

Thermal conductivity

Thermal conductivity of the material. The default value is 401 W/m/K.

## Ports

The block has the following ports:

A

Thermal conserving port associated with layer A.

B

Thermal conserving port associated with layer B.
