Impulsive mass and convective mass
Witryna4. IMPULSIVE & CONVECTIVE NATURAL PERIODS The impulsive period of an elevated tank must be calculated from the combined mass of the structure and the impulsive mass of the fluid acting at a height h i + h s from Figure 2a. In theory, this can be done by adding non-structural mass to an FEA model of a tank and using a … 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 on tank wall and base is given in Figure C-1. …

WitrynaThe impulsive mass mi and the convective masses mc are of fraction of the total liquid mass m. For practical applications, only the first convective mode of vibration needs to be considered in the analysis of mechanical model. The natural period of vibration of the impulsive mass is from 0.1 s to 0.3 s and that of the convective mass from 2 s ... http://nopr.niscair.res.in/bitstream/123456789/169/1/IJEMS%2014%282%29%202407%20133-145.pdf
