Numerical Modeling of Water Waves Interaction With Soft Mud Beds: Based on an Empirical Rheology Model

Qi Peng,Hou Yijun

Strategic Study of CAE 2006, Volume 8, Issue 4,   Pages 39-45

Abstract:

On the basis of the semi-empirical rheology model of soft mud under such oscillatory external forcesnumerical model is developed for simulating the interaction between surface water waves and underlying soft mudA logarithmic grid from the water-mud interface in the vertical direction is employed for numerical treatmentModel verifications are given through comparisons between the calculated and the measured bed mud masstransport velocities as well as the rate of decay of surface wave heights.

A way to explain the thermal boundary effects on laminar convection through a square duct

Liangbi WANG, Xiaoping GAI, Kun HUANG, Yongheng ZHANG, Xiang YANG, Xiang WU

Frontiers in Energy 2010, Volume 4, Issue 4,   Pages 496-506 doi: 10.1007/s11708-010-0020-2

Abstract: A way using the reformulation of the energy conservation equation in terms of heat flux to explain the thermal boundary effects on laminar convective heat transfer through a square duct is presented. For a laminar convection through a square duct, it explains that on the wall surface, the velocity is zero, but convection occurs for uniform wall heat flux (UWHF) boundary in the developing region due to the velocity gradient term; for uniform wall temperature (UWT) boundary, only diffusion process occurs on the wall surface because both velocity and velocity gradient do not contribute to convection; for UWHF, the largest term of the gradient of velocity components (the main flow velocity) on the wall surface takes a role in the convection of the heat flux normal to the wall surface, and this role exists in the fully developed region. Therefore, a stronger convection process occurs for UWHF than for UWT on the wall surface. The thermal boundary effects on the laminar convection inside the flow are also detailed.
