“…strong shock for freely as well as modified case (EOD) is calculated numerically and shown through graph which is depicted in figure (4), which shows that shock is strengthened slowly with increase in the realness of gas with some inflation with effect of overtaking disturbances.…”

“…Variation of shock velocity (U/a 0 ) for cylindrical strong shock imploding in the uniform medium is calculated from equation (35& 46). Initially taking r=1.1, b =0.01, k p =0.1, σ =50, U/a 0 =12, γ =1.36, β=0.1615 and K=9.9531, variation of shock strength with propagation distance (r) has been computed and presented through figures (4). The resultant modification in the strength of imploding shock (U * / a 0 ) under EOD is estimated using equation (46).…”

“…It is found that shock strength increases as cylindrical imploding strong shock wave propagates in a uniform real dusty gas. Figures (4) depicts the variation of shock strength with propagation distance (r) for different values of b . It is observed that increase in strength is enhanced when realness is taken in to account in comparison with ideal gas [figure (4)].…”

“…Figures (4) depicts the variation of shock strength with propagation distance (r) for different values of b . It is observed that increase in strength is enhanced when realness is taken in to account in comparison with ideal gas [figure (4)]. The comparison of modified shock strength under the effect of overtaking disturbances and freely propagation shows that shock strength increases more rapidly under the effect of overtaking disturbances as depicted through figure (4).…”

“…The results accomplished are compared with those for dusty ideal gas Yadav et al 28 . Change in Entropy and temperature just behind the rotating non-ideal gas on propagation of strong shock wave under the effect of overtaking waves is carried out by Gangwar 4 . Convergence of strong shock waves in an ideal gas with dust particles has been tackled by Singh et al 15 .…”

In the present study, we have investigated the motion of cylindrical imploding shock in a real dusty gas having uniform initial density distribution by using (CCW) Chester 2 -Chisnell 3 -Whitham (1958) method. It is considered that the real dusty gas is the mixture of real gas and a large number of small spherical solid particles of uniform size. Initial volume fraction of the solid particles is also assumed constant in this particular study. The particles do not interact with each other therefore their thermal motion is negligible. Initial density of the medium is taken to be constant and medium ahead of the shock front is at rest with small counter pressure. Here the particles behave like a pseudo-fluid. Maintaining the equilibrium flow condition in the flow field, the analytical expressions for the shock velocity, shock strength, pressure, and flow velocity have been derived. The variation of flow variables with propagation distance (r), mass concentration of solid particles in the mixture (k p ) and the ratio of the density of solid particles to the initial density of gas (G) are obtained and discussed through figures. The results accomplished are compared with those for dusty ideal gas Yadav et, al. 28 .
