The simulation of gear lubrication using the meshless CFD software NOGRID points provides valuable insight into the flow behavior inside a gearbox. Lubricants are used to reduce friction and provide cooling. The effectiveness of the cooling process depends on the amount of lubricant and how efficiently it is transported to the hot gear components.

Benefits of NOGRID points CFD software

NOGRID combines the capabilities for handling such complex free-surface flows and moving parts within the domain and allows the simulation of any conceivable gear geometry and operating mode, such as

Fully 3D computation solving the complete Navier-Stokes equations
Injection into the gear box through one or more inlets
Movement and rotation of the gears
Computation of temperature transport in the (solid) gears and in the lubricant
Freely definable material properties by equations or curves for both the gears and the lubricant
Any gear geometry with small gaps or cutouts

Why choose Nogrid?

NOGRID provides professional CFD software for the simulation of fluid flow, heat and mass transfer, and chemical reactions. Its efficient modelling workflow helps engineers analyse flow behaviour, evaluate designs and make informed decisions without creating a conventional volume mesh.

Faster model preparation

With NOGRID, only the geometry boundary needs to be meshed. The finite points inside the fluid domain are generated automatically according to user-defined settings, both at the start of the simulation and during the calculation.

This approach reduces preprocessing effort and makes it easier to prepare complex geometries and cavities for simulation.

Efficient CFD workflow

The modelling process follows four straightforward steps:

Build the geometry. Mesh the boundary. Define the simulation. Start the calculation.

NOGRID is designed to provide short computation times, including for applications involving complex cavities. Engineers can use the resulting data to examine flow distribution and other relevant flow characteristics.

Better insight into fluid-flow processes

CFD solves the fundamental equations governing fluid flow. NOGRID software enables engineers to predict and analyse the behaviour of fluids and related physical processes before or alongside physical testing.

The simulation results can support:

evaluation and comparison of design alternatives
optimisation of construction and operating parameters
improved planning reliability
reduction of development time and testing effort
faster progression from design to market or operation
