Virtual flow rate computing apparatus, virtual flow rate computing method, and virtual flow rate computing program

A virtual flow rate computing method performed by a computer, comprising:

• storing environment information indicating environment of a real space in which a flow rate sensor is instrumented;
• storing physical property information indicating physical properties of fluid to be measured;
• executing a simulation related to measurement of the fluid in a virtual space, which reproduces the real space, by using the environment information and the physical property information;
• and
• computing a virtual flow rate, which is an estimate of an actual flow rate to be actually measured by the flow rate sensor, on a basis of a result of the simulation.

A non-transitory computer readable medium having recorded thereon a virtual flow rate computing program that, when executed by a computer, causes the computer to function as:

• an environment information storage unit which stores environment information indicating environment of a real space in which a flow rate sensor is instrumented;
• a physical property information storage unit which stores physical property information indicating physical properties of fluid to be measured;
• a simulation unit which executes a simulation related to measurement of the fluid in a virtual space, which reproduces the real space, by using the environment information and the physical property information;
• and
• a computing unit which computes a virtual flow rate, which is an estimate of an actual flow rate to be actually measured by the flow rate sensor, on a basis of a result of the simulation.
