Periodic Exponential Shear of Complex Fluids
Chirag Kalelkar, Gareth McKinley
We define a class of flows with exponential kinematics termed Periodic Exponential Shear (PES) flow which involve periodic exponential stretching of fluid elements along with their…
Strain-Rate Frequency Superposition in Large-Amplitude Oscillatory Shear
Chirag Kalelkar, Ashish Lele, Samruddhi Kamble
In a recent work, Wyss, {\it et.al.} [Phys. Rev. Lett., {\bf 98}, 238303 (2007)] have noted a property of `soft solids' under oscillatory shear, the so-called strain-rate frequency…
Statistics of Pressure Fluctuations in Decaying, Isotropic Turbulence
Chirag Kalelkar
We present results from a systematic direct-numerical simulation study of pressure fluctuations in an unforced, incompressible, homogeneous, and isotropic, three-dimensional turbul…
Structural Studies of Decaying Fluid Turbulence: Effect of Initial Conditions
Chirag Kalelkar
We present results from a systematic numerical study of structural properties of an unforced, incompressible, homogeneous, and isotropic three-dimensional turbulent fluid with an i…
Drag Reduction by Polymer Additives in Decaying Turbulence
Chirag Kalelkar, Rama Govindarajan, Rahul Pandit
We present results from a systematic numerical study of decaying turbulence in a dilute polymer solution by using a shell-model version of the FENE-P equations. Our study leads to…
The Decay of Magnetohydrodynamic Turbulence from Power-Law Initial Conditions
Chirag Kalelkar, Rahul Pandit
We derive relations for the decay of the kinetic and magnetic energies and the growth of the Taylor and integral scales in unforced, incompressible, homogeneous and isotropic three…
