Device and method for magnetic field-assisted simulation of zero-microgravity fame synthesis of nanoparticles

A device for magnetic field-assisted simulation of zero-microgravity flame synthesis of nanoparticles, wherein the method comprises a gradient magnetic field device, a combustor and a product collection device;

• the gradient magnetic field device is composed of two magnetic field devices arranged face to face, the combustor is located between the two magnetic field devices, the outlet of the combustor is vertically upward, and the position is below the magnetic field center of the gradient magnetic field device;
• when the use environment is the ground, and the purpose is to simulate a microgravity flame, the direction of the outlet of the combustor is vertically upward, opposite to the direction of a gradient magnetic field generated by the gradient magnetic field device, and at this time, oxygen is subjected to a vertically upward magnetic field gradient force, making the gradient magnetic field force counteract gravity, and the product collection device is located downstream of the flame to collect a synthesized target product;
• when the use environment is a microgravity environment, and the purpose is to simulate a constant gravity flame, the direction of the outlet of the combustor is the same as a magnetic field gradient direction, at this time, oxygen is subjected to a magnetic field gradient force in the same direction as the outlet of the combustor, making the magnetic field gradient force equivalent to gravity, and constant gravity flame synthesis is simulated in the microgravity environment.
