Analysis of the vane rheometer using 3D finite element simulation

3D simulations of the flow of thixotropic fluids, in large-gap Couette and vane-cup geometries

“…Thus, the flow around a vane is indeed similar to the flow around its encompassing cylinder [5]. More recently, 3D calculations have basically confirmed this [6]. Thixotropy may affect these assumptions in the same way it affects flow in any mixer since the structure may not have enough time to reach equilibrium between blades.…”

A numerical study of the flow of Bingham-like fluids in two-dimensional vane and cylinder rheometers using a smoothed particle hydrodynamics (SPH) based method

“…Obviously, the end effect problem associated with the contributions of the applied torque on these upper and lower end surfaces cannot be completely resolved without the help of a 3D numerical simulation. Savamand et al studied Bingham fluids in a 3D vane rheometer by means of finite element simulation [36]. But the applied outer wall angular velocity in their study is much smaller (1.05 rps) compared to those in the present study.…”

Refractive-index and density matching in concentrated particle suspensions: a review

“…If the interblade space does not behave as a rigid body, i.e., if vortices and secondary flows occur, the boundary conditions are changed at the periphery of the blades, which makes it difficult any viscometric treatment of the data. The suspension behavior within the blades have been studied numerically (Savarmand et al 2007;Potanin 2010), but there has been no experimental investigation to date. As far as we know, our experiments are the first report of flow recirculation within vane blades in a Couette cell.…”
