Fluid Dynamic. Force on particles in carrying fluid (liquid)

Click For Summary
SUMMARY

The discussion centers on calculating the force required to stop spherical microparticles (10-15 microns) suspended in a flowing liquid within a pipe. The participant inquires whether the pressure force can be expressed as F = pA, where p is the fluid pressure and A is the area of the particles. The goal is to quantify the pressure force to ensure the microparticles accumulate in a specific location, as they are carried by the fluid stream.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Knowledge of pressure force calculations
  • Familiarity with microparticle behavior in fluids
  • Basic concepts of flow mechanics in pipes
NEXT STEPS
  • Research fluid dynamics equations related to particle suspension
  • Explore methods for calculating pressure force on microparticles
  • Study techniques for particle accumulation in fluid systems
  • Investigate the impact of flow rate on particle behavior
USEFUL FOR

Researchers, engineers, and students in fluid dynamics, particularly those focused on particle transport and accumulation in liquid systems.

Good day to all!
I have a question : We have a flowing fluid ( liquid ) with known pressure, flow in the pipe ( pump is pumping it). There are some spherical microparticles in the liquid, let's say 10-15 microns. I want to create force to stop them moving! Will the pressure force be in the form of F = pA ( p - pressure of the fluid A - area of the particles ). ?

Sorry, if the question is too easy or too fool)))) It is needed for my project.

You'll have to explain what you are doing in more detail .

As I said I want to generate force which is needed to stop microparticles flowing, so that they will accumulate on one place. (I think partciles relatively to fluid do not move, so they are catched by stream). I need to quantify the presure force , because I think it is the greatest acting on particle.
