Induced Mass Motion in Hypersonic Flow Formulas

Induced Mass Motion, added mass or virtual mass is the inertia added to a system because an accelerating or decelerating body must move some volume of surrounding fluid as it moves through it. And is denoted by u'. Induced Mass Motion is usually measured using the Kilogram Square Meter for Moment of Inertia. Note that the value of Induced Mass Motion is always positive.

FAQ

What is the Induced Mass Motion?

Induced Mass Motion, added mass or virtual mass is the inertia added to a system because an accelerating or decelerating body must move some volume of surrounding fluid as it moves through it. Induced Mass Motion is usually measured using the Kilogram Square Meter for Moment of Inertia. Note that the value of Induced Mass Motion is always positive.

Can the Induced Mass Motion be negative?

No, the Induced Mass Motion, measured in Moment of Inertia cannot be negative.

What unit is used to measure Induced Mass Motion?

Induced Mass Motion is usually measured using the Kilogram Square Meter[kg·m²] for Moment of Inertia. Kilogram Square Centimeter[kg·m²], Kilogram Square Millimeter[kg·m²], Gram Square Centimeter[kg·m²] are the few other units in which Induced Mass Motion can be measured.
