Impulsive mass and convective mass

Witrynamass idealization are often treated as two uncoupled single degree of freedom system as shown in fig 2. Thus, total mass is divided into two parts impulsive mass and convective mass. In spring mass model convective massis attached to the wall by the spring having stiffness, whereas impulsive massis rigidly attached to the tank. Witryna24 lis 2024 · Under this concept, a liquid mass that is rigidly connected to the tank wall is termed as impulsive liquid mass. It accelerates along with the tank wall. Whereas, …

WitrynaThe impulsive mass of liquid, mi is rigidly connected to tank wall at height hi (or hi*). Similarly, convective mass, mc is connected to the tank wall at height hc (or hc*) by as spring of stiffness Kc. Representation of Spring Mass Model is Shown in figure-1 and Parameter for Sping Mass Model For Rectangular Tank is shown in fig-2 below. WitrynaThus, total liquid mass gets divided into two parts, i.e., impulsive mass and convective mass. In spring mass model of tank-liquid system, these two liquid masses are to be suitably represented. A qualitative description of impulsive and convective hydrodynamic pressure distribution [4] on tank wall and base is given in Figure 1
