It can be #challenging to obtain #FreeFlight conditions in #WindTunnel #Experiments due to #blockage effects. In our latest work we develop a #SimulationBased methodology to design #Simple #Inserts to tackle this!! mdpi.com/2311-5521/6/8/265 Great work Narges Tabatabaei!! #design
Aerodynamic Free-Flight Conditions in Wind Tunnel Modelling through Reduced-Order Wall Inserts

Aerodynamic Free-Flight Conditions in Wind Tunnel Modelling through Reduced-Order Wall Inserts

Parallel sidewalls are the standard bounding walls in wind tunnels when making a wind tunnel model for free-flight condition. The consequence of confinement in wind tunnel tests, known as wall-inte...

In our latest #paper we used #PhysicsInformed #neuralnetworks (#PINNs) to perform #RANS #simulations without any assumption about the #closuremodel. We obtain stunning results in #complex #TurbulentFlows with #PressureGradient and #Separation ! arxiv.org/abs/2107.10711

In our latest article, Wim Naudé and I discuss seven lessons from the pandemic on data-driven decision making and development. Trust, equality, context, and political leadership are as important, if not more, than technology. Available from @UNUWIDER: wider.unu.edu/publication/da…

UNU-WIDER : Working Paper : Data, global development, and COVID-19

The COVID-19 pandemic holds at least seven lessons for the relationship between data-driven decision making, the use of artificial intelligence, and development. These are that (1) in a global...
