Energy is required to accelerate the fluid to a higher level of total kinetic energy, and this energy is felt on the accelerating body as an additional drag force. It is common to express this additional force in terms of added mass. &#8220;<\/span><\/p>\n<p><\/p>\n<p><span style=\"color: #222222; font-family: Calibri, sans-serif; font-size: 14.6667px;\">So, how to find added mass (virtual mass) in ansys fluent.
