Abstract:
PURPOSEMagnetohydrodynamics (MHD) describes the interaction between electrically conducting fluids and electromagnetic fields, integrating principles from fluid mechanics and electromagnetism. When an electric current passes through a conductive fluid in the presence of a magnetic field, Lorentz forces are generated, producing fluid motion. This phenomenon enables MHD propulsion, a technology for contactless thrust generation in marine and aerospace applications, essentially functioning as a motor with no moving parts. This study investigates the performance of an MHD propulsion system by constructing and testing a device under varying conditions to optimize thrust generation.METHODSThe experiment evaluates the propulsion system under both low and high voltage conditions in different mediums, including saltwater and air. Electrodes are connected to a power source to induce an electric current, while an insulated magnet provides the necessary magnetic field. Experimental trials assess the effects of voltage, electrode arrangement, and fluid conductivity on propulsion performance. Various electrode configurations are explored to optimize thrust generation and efficiency.CONCLUSIONThe results will provide insights into how the design can be optimized, allowing us to potentially upscale the model. These findings will contribute to refining the design and performance of MHD propulsion systems.SIGNIFICANCE/NOVELTYWith improved performance, these results could help advance MHD propulsion techniques, potentially paving the way for their application in naval and space transportation.
