...Pascal Bader; Manuel Pschernig; Wolfgang Sanz; Jakob Woisetschläger; Franz Heitmeir; Walter Meile; Günter Brenn Flow in turbomachines is generally highly turbulent. Nonetheless, boundary layers may exhibit laminar-to-turbulent transition, and relaminarization of the turbulent flow may also occur...
