Free surface flows are extremely complex and appear in various cases such as chemistry, oceanography, thermodynamics and turbomachinery. Their complexity is due to the fact that they are composed of two distinct phases which are only separated by a thin in ...
We study the evolution of a system composed of N non-interacting particles of mass m distributed in a cylinder of length L. The cylinder is separated into two parts by an adiabatic piston of a mass M ≫ m. The length of the cylinder is a fix paramete ...
A numerical model is presented for the simulation of complex fluid flows with free surfaces. The unknowns are the velocity and pressure fields in the liquid region, together with a function defining the volume fraction of liquid. Although the mathematical ...
The aim of this work is to provide mathematically sound and computationally effective tools for the numerical simulation of the interaction between fluid and structures as occurring, for instance, in the simulation of the human cardiovascular system. This ...
The sustainable development of rivers requires a knowledge on the three-dimensional mean flow field and the turbulence in complex morphologies. In a future, the computational capacity will be sufficient to simulate numerically the fine details of the flow. ...
The effects and the consequences of transferring the ignition point of the conventional combustion chamber into a small unscavenged prechamber were evaluted through a numerical simulation based on the CFD-code KIVA- 3V. The prechamber flow characteristics ...
Intube flow boiling experiments for refrigerant R-134a mixed with a lubricating oil are reported for a plain, horizontal tube. The tests were run at a nominal inlet pressure of 3.4 bar over a wide range of vapor qualities at mass velocities of 100, 200, an ...
Experimental test results for flow boiling of pure ammonia inside horizontal tubes were obtained for a plain tube and a microfin tube. Tests were run at a nominal saturation temperature of 4°C, mass velocities from 20-140 kg/m2s, vapor qualities from 1-99% ...
The present work focuses on the flow characteristics and mixing induced by Sulzer SMRX static mixers. It is obsd. both exptl. and numerically that pressure drop increases linearly with velocity for this mixer type and that, as expected, this effect is ampl ...
