## Drilling:Heatgenerationandtransport

Parent Category: Features

If you want to make a thermal analysis by using simulation then our meshless CFD simulation software NOGRID points is a great choice. Based on the geometrical model which can either be imported from your CAD or created with our CAD pre-processor Compass you can generate a computer model of a specific geometry in a very short time (compared to mesh-based methods) and see its thermal characteristics in advance.

NOGRID points shows how the heat is transferred either by heat conduction, heat radiation or by convection means by the flow of a fluid. You can couple also all kinds of heat transfer mechanisms. In the example below you can see a drilling process where two different material transfer the heat: the metal driller and the wooden board which is drilled. At the interface a heat source term is applied which reflects the heat generation caused by the friction between the metal driller and the wood. This model is an example of using two different materials and computes the coupled temperature in both materials by a heat source at the boundary or by a boundary condition.

NOGRID points can perfectly be used for designing and problem solving of heat transfer cases. The speed of the temperature front and the cooling/heating rate can be predicted. NOGRID points helps to understand the flow by visualization of the mass, momentum and heat transfer of single and multiple phases. You receive integral quantities which you can use to analyze the heat exchange efficiency.

What is CFD from NOGRID?

CFD solves the fundamental equations that define the fluid flow process. With CFD software from NOGRID every engineer makes better decisions by predicting, analyzing and controlling fluid flow, heat and mass transfer or chemical reaction. By using NOGRID simulation software you receive information on essential flow characteristics as for example flow distribution. Using it additional to testing and experimentation NOGRID software helps to improve the evaluation of your design – resulting in better construction and operation parameters, increasing planning security and money savings due to faster time to the marketplace for your product or process.
