Abstract
The attenuation of planar shock waves while propagating through dust-gas suspensions was studied experimentally and numerically. The numerical solution was conducted twice, each time using a different correlation for the dust particle drag coefficient. It was shown that when the Reynolds number is relatively high (Re > 200) the solution based on the nonstationary drag coefficient provides better agreement with experimental findings. Also studied was the post shock pressure signature; good agreement was found between experimental and numerical results until the reflected rarefaction wave, from the driver’s end wall, caught up with the transmitted shock wave in the suspension.
