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

QHeat flow
kMaterial thermal conductivity
AArea normal to the heat flow direction
DDistance between layers
TA,TBTemperatures 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

Parameters Tab

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.

Variables Tab

Use the Variables tab to set the priority and initial target values for the block variables prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.

Ports

The block has the following ports:

A

Thermal conserving port associated with layer A.

B

Thermal conserving port associated with layer B.
