Direct Numerical Simulation (DNS) of a spatially-developing turbulent boundary layer is performed with high spatial/temporal resolution. The initial turbulent flow in a zero pressure gradient (ZPG) boundary layer is subjected to a very strong favorable pressure gradient (FPG). The sudden acceleration imposed to the turbulent flow induces quasi-laminarization. An innovative technique has been developed to visualize the hydrodynamic and thermal (passive scalar) structures present in the combined ZPG-FPG computational domain by means of a fully immersive virtual reality (VR) environment.
