In some simulation problems, not only the heat transfer within the fluid plays a role, but also that in the adjacent solid. In such cases, a coupled simulation of heat propagation between the solid and fluid (CHT – Conjugate Heat Transfer) must be performed.
We master such simulations with our open-source tools, e.g. OpenFOAM. For rapid optimization of heating and cooling performance using numerical simulation, we have created additional tools to accelerate the preparation of such simulations.
Stationary and transient 3D simulation of heat propagation in complex components made of different materials. Cooling and heating of components to determine critical heat flows, required cooling loads or e.g. avoidance of thermal stresses. Optimization of component geometries through automated geometry creation and simulation processes.
Gases escaping in the event of an incident (light, heavy) are assessed using CFD, taking into account the nearby and distant environment. Stationary and transient concentration fields show the critical dispersion and its influence at different wind directions. The use of specially developed transient inflow boundary conditions in atmospheric boundary layers enables high reliability of the simulation results.
With 3D simulations, a thermal analysis is performed for cooling various components (electronics, light sources). By quantifying heat radiation and heat conduction, as well as free and forced convection in different cooling concepts, functionality is ensured even during the development process.
The analysis of the flow with heat transfer at various operating points of technical components is the most important step in design and optimization. We have mastered the simulation tools required for this. Improved inflow and outflow and better flow control with minimal pressure losses reduce component and operating costs. Predictions about local thermal stresses can be derived from the 3D simulations.
A reduction in air conditioning energy consumption is possible through efficient and controlled ventilation. Coupled simulations (thermal radiation, conduction, convection) calculate temperatures within the vehicle and on its surfaces due to solar radiation. Optimized software (InsightCAE) for solving transient thermal radiation using CFD, taking into account thermal capacities, enables fast and efficient simulations for the client.
Thermal flow simulation for spatial energy planning
Utilization of a harbor basin for cooling and heating office buildings.
Similar to bolted joints, adhesive joints can also be taken into account in FEM models. We have chosen a modeling technique that also enables a sufficiently detailed evaluation of the stresses within the adhesive layer.
We have more than 10 years of experience in working with the finite element (FEM) code Code Code_Aster for e.g. static and transient analyses with volumes, beams or shells, contact problems, bolted connections, natural frequency analyses.
