Heat Flux and Wall Shear Stress in Large Aspect-Ratio Turbulent Vertical Convection
Emily S. C. Ching
We present a theoretical analysis of large aspect-ratio turbulent vertical convection that yields two relationships between heat flux and wall shear stress, measured respectively b…
Polymers in Fluid Flows
Roberto Benzi, Emily S. C. Ching
The interaction of flexible polymers with fluid flows leads to a number of intriguing phenomena observed in laboratory experiments, namely drag reduction, elastic turbulence and he…
Mean Temperature Profiles in Turbulent Thermal Convection
Olga Shishkina, Susanne Horn, Mohammad S. Emran +1
To predict the mean temperature profiles in turbulent thermal convection, the thermal boundary layer (BL) equation including the effects of fluctuations has to be solved. In Shishk…
Thermal Boundary Layer Equation for Turbulent Rayleigh-Benard Convection
Olga Shishkina, Susanne Horn, Sebastian Wagner +1
We report a new thermal boundary layer equation for turbulent Rayleigh-Benard convection for Prandtl number Pr>1 that takes into account the effect of turbulent fluctuations. These…
Drag Reduction in Homogeneous Turbulence by Scale-Dependent Effective Viscosity
Roberto Benzi, Emily S. C. Ching, Itamar Procaccia
The phenomenon of drag reduction by polymer additives had been studied in simulations on the basis of non-Newtonian fluid mechanical models that take into account the field of poly…
