Heat transfer by convection

Thermal Elements

The Convective Heat Transfer block represents a heat transfer by convection between two bodies by means of fluid motion. The transfer is governed by the Newton law of cooling and is described with the following equation:

$$Q=k\xb7A\xb7({T}_{A}-{T}_{B})$$

where

Q | Heat flow |

k | Convection heat transfer coefficient |

A | Surface area |

T_{A},T_{B} | Temperatures of the bodies |

Connections A and B are thermal conserving ports associated with the points between which the heat transfer by convection takes place. 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.

**Area**Surface area of heat transfer. The default value is

`0.0001`

m^2.**Heat transfer coefficient**Convection heat transfer coefficient. The default value is

`20`

W/m^2/K.

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.

The block has the following ports:

`A`

Thermal conserving port associated with body A.

`B`

Thermal conserving port associated with body B.
