- calculate the flux and current of neutron by MCNP
Guys,I need to calculate the flux and current of neutron by MCNP.So what's the difference between them ,and How to calculate them?
Any ideas?
Any ideas?
Flux is a scalar value, while current is a vector, which has a direction.LeeGru said:Guys, I need to calculate the flux and current of neutron by MCNP.So what's the difference between them ,and How to calculate them?
I need to calculate the ratio between the total neutron current and the total neutron flux.How could obtain this value?Astronuc said:Flux is a scalar value, while current is a vector, which has a direction.
Is the question about neutron current (or particle current) or current density?
Thank you very much.I need to calculate the ratio between the total neutron current and the total neutron flux.How could I obtain this value in MCNPphyzguy said:Flux is a flow/area/time, so in the case of neutrons it would have units like neutrons/(cm^2 - sec). Current is a flow/time, so it would have units like neutrons/second. So the current will be the flux integrated over some surface. How you calculate theme depends on the problem given.
Flux is the measure of the flow of a physical quantity through a given surface. It is represented by the symbol Φ and is measured in units of webers (Wb).
Current is the measure of the flow of electric charge through a conductor. It is represented by the symbol I and is measured in units of amperes (A).
Flux and current are related through Faraday's law of induction, which states that the induced electromotive force (EMF) in a closed circuit is equal to the negative rate of change of the magnetic flux through the circuit.
The main difference between flux and current is that flux is a measure of the flow of a physical quantity (such as magnetic field or heat), while current is a measure of the flow of electric charge.
Flux and current are used in a variety of practical applications, such as in electrical engineering, physics, and materials science. They are essential for understanding and designing devices such as motors, generators, and transformers.
