Description

Technical Field

[0001] The utility model relates to the technical field of experimental devices, in particular to a seawater magnetic fluid propulsion quantitative experimental device. Background Art

[0002] The existing magnetohydrodynamic propulsion demonstrator has some problems in parameter measurement, operational stability and safety. Due to the influence of factors such as electrodes and water surface fluctuations, the measured values of the traditional magnetohydrodynamic propulsion demonstrator will have large fluctuations. The existing magnetohydrodynamic propulsion demonstrator has problems and defects:

[0003] Existing magnetohydrodynamic thrusters have poor operational stability. Existing magnetohydrodynamic thruster demonstrators use a hull design that rises and falls with the water's surface fluctuations when floating on the water, making it impossible to accurately measure thrust and the flow rate within the thruster cavity. Furthermore, this unstable operation makes it difficult to conduct qualitative and quantitative analysis of related physical phenomena. Existing magnetohydrodynamic thrusters also use metal electrodes, which corrode and electrolyze when operating in salt water, resulting in uneven current distribution. Furthermore, wires directly connected to the electrodes can electrolyze because the electrode connections are in salt water, making the current unstable. Utility Model Content
