Abstract
Assuming a similarity hypothesis that achieves the balance of non‐linearity, unsteadiness and dissipative effects, a new type of Burgers' equation is obtained. Consideration is limited to those cases where the singular surface theory predicts no growth of acceleration wave. Two examples are given. In these examples the interpretation of the evolutionary character of shock formation from acceleration waves for a non‐dissipative system fails. The present work provides such an interpretation. Taylor's solution for a plane shock and self‐similar solutions for plane and cylindrical shocks are discussed.
