Simulation Software for Fluids and SolidsSimulation Bulb Heating and Flow Pattern - Thermal Analysis
If you want to perform a thermal analysis of bulb heating, including flow pattern, by using simulation the CFD simulation software NOGRID points is an excellent choice. Based on a geometric model - either imported from your CAD system or created with our CAD preprocessor COMPASS - you can generate a computational model of a specific geometry. Compared to mesh-based methods, this approach significantly reduces setup time and allows you to evaluate the thermal behavior in advance.
Heat can be transferred either through conduction and/or radiation or convection via fluid flow. All heat transfer mechanisms can also be coupled within the simulation. In the example below, the airflow inside a bulb is shown. The screw thread is modeled as a solid (metal), where heat is transferred solely by conduction. A heat source is applied at the tip of the heater, causing the temperature at that point to rise over time. Because the air density depends on the temperature, the air starts to move after a while.
For the heat transport within the air we used a P1 radiation model together with the solving of the usual energy balance (heat conduction and convection). This model is an example of using two different materials and computes the flow pattern in the air and the coupled temperature in both materials.
NOGRID points can perfectly be used for designing and problem solving of heat transfer cases. It allows for precise prediction of the temperature front as well as heating and cooling rates. 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.
Capabilities of NOGRID points CFD software
NOGRID combines capabilities to handle free surface flow and moving parts within the domain, allowing the simulation of any conceivable geometry and operating mode, such as
- fully 3D computation solving the complete Navier-Stokes equations
- easy and intuitive setup for thermal analysis cases
- free definable material properties by equations or curves
- evaluation of chemical reactions and corresponding heat source terms
- open or closed domains, including inflow and outflow areas (non-batch mode)
- moving of parts and flexible thermal contact behaviour
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
