Although I have studied it before, I still don’t understand what fluid mechanics mainly focuses on, what role it plays in industry, and whether \"drag\" is simply another term for resistance. I hope everyone can help! Thank you very much for all your answers. Could you please explain this concept of ‘traction’ in more detail? I remember there’s also something called ‘stress’; I know what pressure is, but my understanding of traction is still unclear. Moreover, I can’t type the character for ‘traction’ without the handle symbol on my keyboard, so I can only use this alternative character. It’s pretty much the same, I hope you understand
I didn’t understand it either. The drag force should be similar to the surface resistance. If there is any guidance to be had, it should be related to the flow conditions inside those large reactors; things like Fluent simulations, and it’s likely that fluid dynamics is the key factor here. .
It has a wide range of applications, such as calculating the flow velocity, pressure, and flow conditions of fluids in pipes, as well as pipeline resistance and pressure drops
Fluid mechanics studies the laws of fluid motion (the interactions between fluids and solid walls, between fluids themselves, and between fluids and other forms of motion), as well as the laws governing heat and mass transfer in fluids. In my opinion, the most widely applied area in the chemical industry is resistance calculation.
Isn’t chemical production involved in many pipes, often for gaseous and liquid phases? Doesn’t that relate to knowledge of fluids?
Thank you all for participating; it seems I need to learn more!
Fluid mechanics is a branch of mechanics that primarily studies the static and dynamic states of fluids, as well as the interactions and flow patterns that occur when there is relative motion between fluids and solid boundaries. The fluids most studied in fluid mechanics are water and air. Its main foundations are Newton’s laws of motion and the law of conservation of mass; thermal mechanics knowledge is often also required, and sometimes the basic laws of macroscopic electrodynamics, constitutive equations, as well as fundamental knowledge of physics and chemistry are needed as well. Knowledge of fluid mechanics is required for calculating fluid flow within pipes, pipeline resistance and pressure drop, as well as particle sedimentation.
