Polymer Effects on Heat Transport in Laminar Boundary Layer Flow
Roberto Benzi, Emily S. C. Ching, Vivien W. S. Chu
We consider a laminar Blasius boundary-layer flow above a slightly heated horizontal plate and study the effect of polymer additives on the heat transport. We show that the action…
Heat transport by laminar boundary layer flow with polymers
Roberto Benzi, Emily S. C. Ching., Vivien W. S. Chu
Motivated by recent experimental observations, we consider a steady-state Prandtl-Blasius boundary layer flow with polymers above a slightly heated horizontal plate and study how t…
Understanding the different scaling behavior in various shell models proposed for turbulent thermal convection
Emily S. C. Ching, H. Guo, W. C. Cheng
Different scaling behavior has been reported in various shell models proposed for turbulent thermal convection. In this paper, we show that buoyancy is not always relevant to the s…
Refined similarity hypotheses in shell models of turbulence
Emily S. C. Ching, H. Guo, T. S. Lo
A major challenge in turbulence research is to understand from first principles the origin of anomalous scaling of the velocity fluctuations in high-Reynolds-number turbulent flows…
Ultimate-state scaling in a shell model for homogeneous turbulent convection
Emily S. C. Ching, T. C. Ko
An interesting question in turbulent convection is how the heat transport depends on the strength of thermal forcing in the limit of very large thermal forcing. Kraichnan predicted…
Anomalous Scaling and Refined Similarity of an Active Scalar in a Model of Homogeneous Turbulent Convection
Emily S. C. Ching, W. C. Cheng
Anomalous scaling in the statistics of an active scalar in homogeneous turbulent convection is studied using a dynamical shell model. We extend refined similarity ideas for homogen…
