Videos

Our videos show the application of fluid mechanics in practice. Solving a wide variety of fluid mechanics problems led to a profound fluid mechanics know-how.

 

Our videos at a glance

We would like to be the partner for our customers for processing fluid mechanical tasks and supporting their innovations and developments by our experience, knowledge and creativity.

The combination of numerical methods in the planning phase, the measurement technique in practice and the use of our fogging devices lead us to the treatment of the interesting tasks in the shown videos.

 
Simulation of the Kármán Vortex Street

Simulation of the Kármán Vortex Street with the tool OpenFoam.

 
FlowPointer - How do I use the small fog generator?

Professional flow visiualization with the fog generator FlowPointer of Tintschl BioEnergie und Strömungstechnik AG.

 
Laser light cut

The video shows the components, the assembly and the operation of a system for the creation of laser light cuts. The system was developed as part of a diploma thesis in cooperation with the Coburg University.

 
Simulation FlowLiner

Flow visualization of an aerofoil in the wind channel at the Technische Hochschule Nürnberg. The video shows the comparison of the real airfoil, with an flow visualization with the fog generator "FlowMarker®"  with a numerical calculation of the same areofoil.

 
Flow simulation of a multi-jet impeller water meter

The impeller meter shown in the video is used for measuring water consumption in private households. Through simulation, this multi-jet impeller meter was recreated on a computer.

With a time-dependent investigation, the flow-induced movement of the impeller was recalculated and the resulting torque was determined. In addition, the symmetrical incident flow and the resulting uniform incident flow of the impeller can be represented and investigated effectively by applying numerical methods.

 
Flow simulation of a single-jet impeller meter

The impeller meter shown in the video is used for measuring water consumption in private households. Through simulation, this single-jet impeller meter was recreated on the computer.

With a time-dependent investigation, the flow-induced movement of the impeller was recalculated and the resulting torque was determined. In addition, the tangential inflow of the impeller can be represented and investigated effectively by applying numerical methods.

 
The Robustness Test with CFD

The numerical calculation of indoor air flow supports both in the planning phase and in the processing of emerging issues.

 
Simulation of Oil Flow in a Gearbox

The video shows a simulation of oil flow in a gearbox. This fluidic investigation provided explanations to unexplainable phenomena occurring in practice.

It shows the transient simulation of a gearbox while acceleration followed by a bend to the right. It was thus possible to precisely track the exact flow of the oil and optimize the design of the gearbox.

 
Flow simulation in a vehicle interior

The video shows the flow pattern and temperature distribution in a vehicle interior. The driver's seat heated up due to solar radiation. The simulation shows the behavior after switching on the vehicle air conditioning.

The video shows the change of the flow and the temperature inside the vehicle. The temperature in the vehicle seat is considered separately. The changes in this temperature are shown in the half-section from the side.

 
CFD Simulation Indoor Air Flow


The video shows cooling of a vehicle seat. The seat is heated up by the sun. The simulation shows the behavior after switching the vehicle air conditioning on. The temperature change on the seat surface can be observed.

The contact surfaces between a person and the seat are of particular interest. The temperature distribution and change is also shown.

 
Flow visualization with a fog probe in the wind tunnel

The video shows an airfoil in a wind tunnel with a lateral flow. The flow is visualized by the fog probe FlowLiner ® from Tintschl BESt AG and the newly developed FlowTracer HS. This makes possible to examine the flow pattern in various positions of the wing and to explain special features such as vortex formation, stall and the  rossing of flows.

The recordings were made in the wind tunnel test rig of Technischen Hochschule Nürnberg.

 
Reproducing the real  robustness test by applying CFD

During type testing according to DIN EN 14175 Part 3, the robustness test often determines whether a fume cupboard complies with the required standard values.

In addition to checking the limit values in our measurement laboratory, further fluidic findings can be obtained and the fume cupboard can be further optimized.
