Discussion Overview
The discussion focuses on the influence of non-Newtonian fluid properties, specifically yield stress and shear-thinning behavior, on hydrostatics compared to Newtonian fluids. It explores how these properties affect pressure distribution in Bingham plastic fluids and their implications for the design of storage tanks, particularly regarding wall forces and the center of pressure.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants inquire how hydrostatic pressure distribution changes for Bingham plastic fluids compared to Newtonian fluids, particularly regarding the role of yield stress.
- One participant suggests that the pressure distribution might involve adding the yield stress to the standard hydrostatic pressure equation, but expresses uncertainty about the complexity of this relationship.
- Another participant believes that the hydrostatics of both fluid types should be the same in stable equilibrium, as both fluids would be at rest.
- It is noted that the filling method of the tank and the presence of residual stresses in the solid plug may influence the center of pressure and wall forces.
- Participants express uncertainty about the specific calculations or definitions related to wall forces and the center of pressure in the context of Bingham plastics.
Areas of Agreement / Disagreement
Participants express differing views on whether the hydrostatic behavior of Bingham plastic fluids is fundamentally different from that of Newtonian fluids. There is no consensus on how to approach the calculations for wall forces and center of pressure in Bingham plastics.
Contextual Notes
Participants acknowledge limitations in their understanding of the concepts, particularly regarding the definitions and calculations related to wall forces and center of pressure in Bingham plastic fluids.
