Simulation Water Wave Around Cylindrical Body

Figure 4: Animation of the water wave around a cylinder

This example shows the possibilities of simulation of  water waves using the meshless CFD software NOGRID points. Shown on the left is an ocean water wave slamming against and flowing around a cylindrical body (building).

Due to the special architecture of the cylinder the wave front becomes a special characteristic which is typical for such flows. Integration of the forces acting upon the cylinder helps to evaluate the buildings' stability in many different weather conditions. The effectiveness of architectural improvements can be judged quickly. 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 can be used for designing building or structures which are forced by water waves. The software 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 forces acting on the walls efficiency.

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 free surface flow case
  • free definable material properties by equations or curves for each fluid
  • large geometries with small gaps or holes
  • moving of additional parts or boundaries
  • any material combination or the fluids and for the building material

 

Nogrid's strengths

NOGRID's particular strengths 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.

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 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.
