Hey, I was trying to find out how to calculate velocity of water through a magetohydrodynamic thruster given current, dimensions, pure water etc and google did not help me in my search, any help appreciated.
Magnetohydrodynamics, also known as MHD, is a branch of physics that studies the dynamics of electrically conducting fluids in the presence of magnetic fields. It combines principles from both fluid dynamics and electromagnetism to understand how magnetic fields affect the motion of fluids and vice versa.
MHD has a wide range of practical applications, including in the design of fusion reactors, propulsion systems for spacecraft, and the study of astrophysical phenomena such as the solar wind and magnetospheres. It is also used in industrial processes such as metal casting and mineral processing.
Some key equations in MHD include the Navier-Stokes equations, which describe the motion of a fluid, and the Maxwell equations, which describe the behavior of electric and magnetic fields. MHD also involves other equations such as Ohm's law and the continuity equation, which describe the behavior of charged particles in a fluid.
One challenge in studying MHD is the complexity of the equations involved, which often require numerical methods for solving. Another challenge is the highly nonlinear nature of MHD, which can make it difficult to predict the behavior of a system. Additionally, the presence of turbulence and other instabilities can complicate the analysis of MHD systems.
There are still many unanswered questions in MHD research, including the role of magnetic reconnection in plasma dynamics, the behavior of MHD systems at extreme conditions, and the interactions between MHD and other physical processes such as turbulence. Additionally, there is ongoing research in developing new and more accurate models for MHD systems.
