College, Kotdwar (Garhwal) <p style="text-align: justify;">In the present paper effect of overtaking disturbances on the freely propagation of converging strong spherical shock through a rotating dusty gas is studied by a technique developed by Yadav¹⁶. The dusty gas is assumed to be a mixture of a perfect gas and small solid particles. Assuming an initial density distribution law as r₀=r_cr^-a,<strong> </strong>where r_c is the density at the axis of symmetry and a a positive constant, the analytical relations for flow variables modified by overtaking disturbances are obtained. The variations of flow variables with (i) propagation distance, (ii) mass concentration of solid particles in the mixture, (iii) specific density G and (iv) angular velocity W, are obtained. The results obtained here are also compared with those for a freely propagating shock.</p> https://ultraphysicalsciences.org/paper/1070/ Converging shock waves dusty gas rotation.
