For CFD liquid sloshing simulations, fine computational mesh resolutions are typically required to model the flow within small passages or orifices found in fuel tanks. This work presents a method of replacing elements with large one-dimensional that integrate seamlessly standard finite volume intended advantage reducing overall cost simulations. These conserve mass and momentum for two-phase i...

We present a method for charge mixing in self-consistent density functional calculations which uses the Thomas-Fermi-von Weizsäcker equation to solve implicitly for the charge density response function to the potential. This approach has significant improvements over existing methods, particularly for inhomogeneous systems with large unit cells which commonly suffer from poor convergence due to...

Abstract Sloshing is relevant in several applications like ship tanks, space and automotive industry seiching harbours. Due to the relationship between sloshing motions possibility of structural damage, it important represent this phenomenon accurately. This paper investigates at shallow liquid depths a rectangular container using experiments RANS simulations. Free forced sloshing, with without...

SPH is a relatively new, rapidly evolving Lagrangian meshless method that is currently being applied in a large variety of cases, ranging from astrophysics to nuclear engineering. However, most of these cases have been treated so far as single phase cases, therefore limiting both the accuracy of the method and the range of cases that can be solved and importantly the physics captured. However, ...

Abstract All aircraft are subject to a range of loading throughout ground and flight operations, which ultimately define the sizing weight structure. Active passive loads alleviation technologies provide an approach reduce dynamic arising from atmospheric gusts turbulence, leading more fuel-efficient designs. Within H2020 SLOWD project, fuel sloshing is being considered as method for alleviatin...

Ethiopia imports all fuel and crude oils from abroad at high cost, transportation of these fluids has been carried out by using various capacity road heavy-duty truck vehicle. Most tanker accidents happen during turning because the fluid splashing in partially loaded tanks uniqueness carrying liquids. This is a result fact that current baffle configurations are effective reducing sloshing when ...

The elevated reinforced concrete tanks assessed in the current work were subject of a nonlinear sloshing analysis resulting from fluid–container interactions. primary response quantity interest was height free surface sloshing. To achieve this aim, effect liquid contents on seismic behavior subjected to various sets far- and near-fault ground motions measured. variables considered study include...

Sloshing is a common flow phenomenon in liquid cargo tanks and has great negative impact on the stability safety of ship navigation. It important to understand sloshing process under excitation complex external conditions for transportation cargo. In this paper, characteristics tank are studied combination roll surge. The pressure distribution at different positions discussed, along with influe...
