If you want to perform a simulation of a heat exchanger (type floating) for the purpose of a thermal analysis then our meshless CFD 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 preprocessor 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 by means the flow of a fluid. You can couple also all kinds of heat transfer mechanisms. In the example below you can see a floating heat exchanger with two fluids. This model gives you a better understanding of the heat exchange process and helps to improve your heat exchanger design regarding efficiency and costs. If something should be missing for your purposes, please let us know, we can easily implement additional requirements.

NOGRID points can perfectly be used for designing and problem solving of heat exchangers. The thermal homogenizing and the cooling/heating rate can be predicted. The software helps to understand the flow by visualization of the mass, momentum and heat transfer of single and multiple phases in the heat exchanger. You receive integral quantities which you can use to analyze the heat exchange efficiency. Additionally, animations of particle paths can easily be performed (see figure 4).

NOGRID unites abilities to handle multi-phase flows and allows the simulation of any conceivable geometry and operation modes such as

  • computation is in full 3D solving complete Navier-Stokes-Equations
  • easy and intuitive setup of the multi-phase flow case
  • free definable material properties by equations or curves for each fluid
  • large geometries with small gaps or holes
  • open or closed domains including moving of additional parts
  • any material combination for the fluids and for the heat exchanger material


Nogrid's strengths

Particular strengths of NOGRID's fluid flow CFD software are the rapid preprocessing (no fluid grid needs to be generated, only the boundary mesh, inner finite points are generated automatically depending on User setting initially and during computation), and the outstandingly short computation time even for complicated cavities.
As you can see in the image below, the boundary of the geometry still requires a mesh to allow the interior finite points to detect the boundary. The boundary must therefore be meshed and the finite points inside are automatically generated during the simulation controlled by User specifications.
Easy Modelling

Easy and fast modelling: Build geometry, mesh boundary, setup the case and start computation

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 software for flow modeling 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.
