If what you are doing is simulating a droplet of water, initially suspended in oil, falling down into a water layer and impacting the oil-water interface then you should be able to get what you want by clipping by alphaoil=0.5 which will clip off everything that is on the oil side of the interface(s) and then color the remaining parts, which are now just water only as a solid color.1 RVA: A Plugin to ParaView 3.14 for Improved Reservoir Visualization and Analysis USER MANUAL Version September, 2015 D. This is a full 360-degree model and so I also clipped in the vertical direction to show the cross-section. In this case, I have clipped by alphaair (I think I used a small value of 0.1 to capture more of the liquid near the spinning inner cylinder) and then colored the result by alphaoil. For example, here is an image from a recent paper (see this thread for links) in which I am simulating three phases (air, water, oil) but maintaining a sharp interface for air-water and air-oil only. you have set the interfaceCompression coefficient for the (water oil) pair in constant/transportProperties to be 0) then you would want to color by the dispersed phase fraction. On the other hand, if you are mixing the two fluids Euler-Euler style (i.e. For example, in your second image you have clipped by alphaoil but then colored by alphawater which isn't so useful if the interface is staying sharp. If you have just the two phases (oil, water) AND you are using interfaceCompression between them (this can be switched off in multiphaseEulerFoam) then you could use a clip on the scalar alphawater (0.5 is fine) and then color as a solid color. Well, it sort of depends on what you are actually trying to simulate which is still not super clear to me. Wondering I chosen the wrong value for clip scalars, however, before knowing the mechanism, I am not sure what is right to choose.ītw, the solver what I used is multiphaseEulerFoam I use the same method, but this time I can only see the water base but without and different colored oil on surface of the water. The rest is to use the clip to scalar optionīUT, only I can see the water-in red color when it falls into the oil, how can I see the effect like the one plotted by the contour but with different color? If I use contour the result would be like the first photo I use three value 1.0 1.1 1.2 to make sure you can see the surface of the oil. Can you please explain how this value matters? You are correct, the base is oil and the droplet is made of water.įor the clip scalar, I am not sure what should I choose( alphas, alpha oil or alpha water?) to render and what value should I put ( I tried alphoil with value of 0.5 as in photes). Thanks very much for the help and you really gave me a good way to start with. īut CFX or Fluent can handle this easily in their pre-process.while its tough in OpenFOAM.ĭo you know how to handle this? by the way, you have so many cells, how small is your time step? and which program are you use to generate mesh? but this innerface should not emerge in the boundary dictionary.you can see it here. There is always an innerface which can not be deleted. such as unstructured mesh in rotatezone and structured mesh in stationaryzone. It works too but a smaller time step.īut problems arise when I am using hybird meshs. or just generate tow bodies called rotate and stationary. then set the innerface as interior or interface. for example: I generate block in the entire zone and name it seperately rotatezone the stationaryzone. I generated mesh via ICEM, but I can only make the solver working without exploding by the same mesh in ratate zone and stationary zone. I am do the simulation using MRFInterFoam or twophaseeulerfoam, but I have big problems in MRFzones. Thank you Kent, Thats a splendid post-processing job u have done. "Open-Source CFD Simulations of Liquid–Liquid Flow in the Annular Centrifugal Contactor," Sep. The mesh had ~2.5M poly cells (made in ccm+). This was done using multiphaseInterFoam, version 1.5.x.
