WitrynaAbstractThis work is focused on the effect of heat and mass transfer with unsteady natural convection flow of viscous fluid along with ramped wall temperature under the assumption of the slip wall condition at the boundary.Analytical solutions are obtained by using Laplace transformation to the non-dimensional set of governing equations ... 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. … 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.

Based on the linear potential theory, Graham and Rodriguez (1952) first derived the exact solution of the equivalent mechanical model for a sloshing fluid in a rectangular tank. The parameters of the equivalent model included the impulsive and convective masses along with their locations and the sloshing … WitrynaImpulsive hydrodynamic pressure acts on tank walls due to Impulsive liquid mass. Liquid mass in upper region of tank experience sloshing motion. This mass is termed …

Witrynamodes set up by this mass are called the impulsive modes. Another part of the liquid mass undergoes vibration due to it’s inertia properties and cause sloshing. This part … Witryna1 sie 2024 · The first-order convective mass α 11, the corresponding spring stiffness κ 11 and the impulsive mass α 10 for different non-dimensional fluid heights β 1 with β 2 = 0.5, 0.8 and γ =0.3, 0.5 are plotted in Fig. 5 (a). It can be seen from Fig. 5 (a) that the higher fluid height implies smaller α 11 and greater α 10.In Fig. 5 (a), κ 11 reaches the …

WitrynaRevathi et al. [Citation 27] conducted a study on forced convective flow through a yawed cylinder, taking temporal variations and non-uniform suction into account (blowing). It is important to know the impact of sudden change in the fluid motion (impulsive motion) and roughness on the fluid flow characteristics. 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.
