Taking initial density distribution (i)&nbsp; and&nbsp; (where r&#39; is the density at the axis of symmetry, &#39;l&#39; is a non-dimensionalising constant and w is a constant), the analytical expressions for flow variables have been derived representing Free Propagation(CCW Description) and eod on CCW^1-3 results. Permissible shock front locations have been obtained ensuring the validity of this <em>study for density increasing and decreasing regions, as well.</em></p> <p>&nbsp;</p> <p><img src="file:///D:/atif/Drive%20E%20data/desktop%20data/Business/journal/JUSPS%20A&amp;B/JUSPS/21(3)/AbstWMF9.JPG" style="height:18px; width:53px" />.</p> https://ultraphysicalsciences.org/paper/1181/ Effects overtaking disturbances;
