The study of physic fluid for a liquid draining inside a tank is easily accessible using numerical simulation. However, numerical simulation is expensive when the liquid draining involves the multi-phase problem. Since an accurate numerical simulation can be obtained if a proper method for error estimation is accomplished, this paper provides systematic assessment of error estimation due to gri...

In the building sector, 40% of final energy is used for heating and cooling. Up to 75% this in residential buildings. It necessary take a step forward reduce share consumption, particular through use efficient technologies their integration into system renovation buildings, which major challenge future research field. An important technology achieving goal heat storage, where phase change mater...

In this study, the liquid sloshing in a cylindrical tank considering soil–structure interaction and undergoing horizontal excitation is investigated analytically. Multiple rigid annular baffles are positioned on wall to mitigate sloshing. Firstly, combined with subdomain partition method for sloshing, complex domain partitioned into simple subdomains single condition boundary. Based continuity ...

For the intermittence and instability of solar energy, energy storage can be a good solution in many civil industrial thermal scenarios. With advantages low cost, simple structure, high efficiency, single-tank system is competitive way (TES). In this study, two-dimensional flow heat transfer model cylindrical tank with water as fluid (HTF) developed, which effects time, velocity, height-to-diam...

The gravitational water vortex turbine is an alternative to renewable energies, it transforms the hydrokinetic energy of rivers into electric and does not require a reservoir. According studies carried out, hydraulic efficiency can increase or decrease according geometrical configuration. This paper presents numerical (CFD) analytical comparison between conical cylindrical designs for outlet. r...

Several industrial fields require mixing and mechanical agitation processes. This operation is mainly used to enhance heat mass transfer inside stirred tank systems improve the degree of homogeneity obtain a high-quality final product. The main goal this research paper analyze thermal hydrodynamic behavior non-Newtonian nanofluid (Bingham–Papanastasiou–Al2O3) symmetrically tank. A 3D numerical ...

Ultrasonic teclmiques have been used to directly and non-intrusively measure the circulation of free surface vortices. All experiments were performed in a vertical cylindrical tank with a central drain and a tangential inlet The circulation was measured on a closed triangular path by measuring the difference in upstream and downstream transit-times. Circulation was measured as a function of the...
