If you want to perform a simulation of a heat exchanger (type floating) for thermal analysis, our meshless CFD software NOGRID points is an excellent choice. Based on the geometric model - either imported from your CAD system or created with our CAD preprocessor COMPASS - you can quickly generate a computer model of the specific geometry. Compared to mesh-based approaches, this method is significantly faster an allows you to evaluate the thermal behavior in advance.

Advantages of simulating heat exchangers with NOGRID points

NOGRID points visualizes heat transfer through heat conduction, radiation, and convection via fluid flow. All types of heat transfer mechanisms can be coupled within the simulation. In the example below, a floating heat exchanger with two fluids is shown. This model provides deeper insight into the heat exchange process and supports the optimization of your heat exchanger design in terms of efficiency and cost. If you have specific requirements that are not yet covered, please let us know - we can easily implement additional features to meet your needs.

NOGRID points is ideally suited for the design and analysis of heat exchangers. It enables accurate prediction of thermal homogenization as well as heating and cooling rates. The software helps to understand the flow by visualizing mass, momentum, and heat transfer for both single-phase and multiphase systems within the heat exchanger. It also provides integral quantities that can be used to evaluate heat exchange efficiency. In addition, particle path animations (see Figure 4).

Capabilities of NOGRID software

NOGRID integrates abilitiy to handle multiphase flows and supports the simulation of any conceivable geometry and operating mode 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 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.
