Abstract
The pressure modulation of a weak shock wave induced by a Nd:YAG laser pulse when passing across a turbulent slit jet was experimentally investigated. With the slit jet the peak overpressure became smaller by an average of 12%, with a standard deviation of 27%. Clear relationships were obtained between the overpressure history and the experimentally observed shock front deformation, which was visualized as differential schlieren images. The peak overpressure was increased when the originally spherical blast wave front was locally flattened, whereas it was decreased when a hump in the shock wave front was formed.
