Axisymmetric Taylor-Couette Swirl Flow CFD Simulation from FEATool Multiphysics. In this simulation, for the axisymmetric Navier-Stokes equations including swirl effects, the rotational velocity is being continuously increased. This causes tangential Taylor vortices to appear after a certain point. The flow is still laminar but exhibits length wise vortices. As the velocity is increased further, they destabilize and start to travel in the axial direction. Around t = 10 s when the stable Taylor vortices appear at about a Taylor number of 1500-1700 which is in good agreement with theory. Around t =20 s Taylor vortices start moving length wise. #mechanicalengineering #mechanical #aerospace #automotive #cfd

The aerospace and defense industry requires circuit boards that can withstand the extreme conditions found in planes, satellites, space shuttles, and control towers. With modeling and simulation, these boards can be developed and tested before production even begins. In this video, Russell Rioux of Northrop Grumman discusses how they use the COMSOL Multiphysics software to perform thermal analyses of circuit card assemblies and how they successfully reduce model meshing with the software’s image processing capabilities.

This will be a very interesting and exciting webinar on Simulation and the future of flight.

The aerospace and defense industry faces ongoing challenges in ensuring accurate and efficient simulations, crucial for speeding up the design process. Techniques have been developed to automate mesh generation to improve flow-field predictions. Traditionally, creating meshes for computational fluid dynamics (CFD) required a deep understanding of physics and adherence to complex best practices.

🖥 Direct numerical simulation of twin-fluid atomization in the annular flow regime Three-dimensional direct numerical simulations of a twin-fluid atomizer in the annular regime are performed to study the multiphase instabilities, shock waves, and the onset of atomization. The injection involves a sonic air jet surrounded by an annular layer of liquid. The expansion of the sonic jet results in shock wave formations, Rayleigh–Taylor, and Kelvin-Helmholtz instabilities that cause the annular liquid sheet disintegration into ligaments and droplets. Three simulations at varying driving pressure; 0.55 MPa, 0.8 MPa, and 1.2 MPa, showed an interesting change in the dimensions of the mach disk shock-wave as well as the deformation of the liquid sheet.
