How to Model High Viscosity Layered Waste Pumping in CFD?

[sergkras2000]

Please, can somebody help in a problem related to FD and outlined below.
I need to formulate a problem for the following question: modeling of liquid flows during a process of pumping from open storages. A liquid is high viscous waste similar to highly viscous oils. It is layered waste from coke making and petroleum refining plants. The waste are stored in nature reservoirs like a lagoons having three layers and it must be pumped with partly heating in predetermined depth.
Is the following formulation right and can be solved using current CFD codes: "Investigation of liquid flow of viscous incompessible layered waste in 2-D stationary laminar flow during a process of pumping from storages of industrial plants"?
Please, maybe somebody can suggest how to correct or complicate the formulation, may be by addition heating process problem or other definition for the Navier-Stokes equations?

Thank you in advance!

Maybe it is a bit complex for me giving you the OK for your problem. You should specify more the geometry and flow.

At first sight I think that Incompressible Flow N-S equations are accurate for your purposes. Don't worry about heating. The heating will only affect to temperature field, only and only if the viscosity doesn't depends on temperature. If viscosity depends on temperature, then both momentum, continuity and energy equations are coupled.

The formulation for the CFD problem you have outlined seems appropriate and can be solved using current CFD codes. However, there are a few ways in which you can further refine and complicate the problem to make it more challenging and realistic.

Firstly, you can consider incorporating turbulence effects into the model, as real-life flows are often turbulent in nature. This would require the use of the Reynolds-averaged Navier-Stokes (RANS) equations and a suitable turbulence model.

Secondly, you can also include the effects of heat transfer in the problem. This would involve solving the energy equation along with the Navier-Stokes equations, and considering the temperature variations in the liquid as it is being pumped from the storage.

Additionally, you can also consider the presence of solid particles in the liquid waste, which can affect the flow behavior and require additional modeling techniques such as the Euler-Lagrange approach.

Overall, incorporating these additional complexities will make the problem more challenging and closer to real-life scenarios, and will require advanced CFD techniques and codes to solve it accurately. I hope this helps in refining your CFD formulation problem. Good luck!
