Roll-Waves on a Non-Newtonian Mud Layer

by Chiu-on Ng, Massachusetts Inst of Technology, Cambridge, United States,
Chiang C. Mei, Massachusetts Inst of Technology, Cambridge, United States,



Document Type: Proceeding Paper

Part of: Engineering Mechanics

Abstract:

This article extends the theory of roll-waves due to Dressler (1949) to a thin layer of mud modeled as a power law fluid. Roll-waves are periodic bores moving at a constant velocity down an incline. Basic equations for long waves are derived. Particular discussions are given on the condition for the critical flow.
