Multilayer particle deposition and resuspension between periodic steps in a turbulent channel flow was experimentally studied. A particle laden turbulent flow in a horizontal channel was generated by means of a small-scale wind tunnel. Periodic steps were placed on the channel floor to induce a complex flow field characterised by flow separations, recirculation and reattachment zones.The turbulent...
Imaging of complex and dynamic processes such as two- or multiphase flows with high structural as well as temporal resolution has always been a challenging task. In recent years, the electron beam X-ray computed tomography technique has been developed towards a powerful imaging tool, which reaches frame rates of 8000 fps in 2D and 1000 fps in 3D. In this paper, the latest developments as well as selected...
Wielu producentów szyb zespolonych czeka ze złożeniem deklaracji CE na ostatnią chwilę. Nie jest to bynajmniej wynikiem zaniedbania. Dzieje się tak, moim zdaniem, z powodu wysokich kosztów, niskiej orientacji producentów w wymaganiach norm serii PN-EN 1279 oraz braku orientacji w praktycznym sposobie wdrożenia Zakładowej Kontroli Produkcji. Chociaż temat ten poruszany był wielokrotnie w czasopismach...
