FLUID ANALYZING METHOD

摘要

A first unknown physical property value in the vicinity of an inter-fluid interface is calculated using an advection equation and based on the known physical properties of respective fluids forming the interface, a first unknown fluid behavior value representing an behavior in the vicinity of an inter-fluid interface is calculated using the control equations of fluids and based on the calculated first unknown physical property, an interface function in the vicinity of an inter-fluid interface is calculated using a digitizer method and based on the calculated first unknown fluid behavior value, and the calculated interface function is converted using a smoothing method. A second unknown physical property in the vicinity of an inter-fluid interface is calculated using an advection equation and based on the known physical properties of respective fluids forming the interface and the converted interface function, and second unknown fluid behavior value representing an behavior in the vicinity of an inter-fluid interface is calculated using the control equations of fluids and based on the second unknown physical property and the first unknown fluid behavior value.
