The influence of the mixing time in the rheological behavior of cement pastes
Rheology has the purpose to study the flux and deformation of materials when submitted to some tension or outer mechanical solicitation. In practice, the effective scientific field broached by rheology is restricted only ...
Numerical investigation of three dimensional viscoelastic free surface flows: Impacting drop problem
This work presents a numerical investigation of three dimensional viscoelastic free surface flows. In particular, using two different numerical methodologies, we have simulated a typical free-surface benchmark flow problem: ...
NUMERICAL SIMULATION OF THE WEISSENBERG EFFECT
(Int Center Numerical Methods Engineering, 2015-01-01)
Weissenberg effect, or Rob-Climbing experiment, is encountered in many important industrial applications involving mixing process. In this experiment we insert a rotating rod into a container with viscoclastic fluid. The ...
NOISE GENERATED BY CAVITATION IN ORIFICE-PLATES WITH SOME GASEOUS EFFECTS.
An experimental investigation of the noise generated by cavitation in turbulent shear flows produced by confined sharp-edge orifice-plates is reported. The acoustic source strength of cavitation was determined by means of ...
Assessment of numerical techniques for micro-drop fluid mechanics
(Instituto Balseiro - Centro Atómico BarilocheBariloche, 2014-09-23)
Are currently available CFD techniques able to model the motion of a submilimiter-scale liquid drop falling in another (quiescent) liquid? In this work we define a very simple two-dimensional test: An initially circular ...
