A modified moving particle semi-implicit (MPS) method based on GPU acceleration technique is applied to simulate three-dimensional (3-D) free surface flow by using our in-house solver MPSGPU-SJTU in this work. In order to validate MPSGPU-SJTU solver, 3-D dam break and sloshing, two typical violent flows with large deformation and nonlinear fragmentation of free surface are simulated. For dam br...

Linear mountain wave theory is used to derive the general formulas of the gravity wave momentum flux (WMF) and its vertical divergence that develop in directionally sheared flows with constant vertical shear. Height variations of theWMF and its vertical divergence are studied for a circular bell-shapedmountain. The results show that the magnitude of the WMF decreases with height owing to variab...

Carotid-femoral pulse wave velocity is an established method for characterizing aortic stiffness, an individual predictor of cardiovascular mortality in adults. Normal pulse wave velocity values for the pediatric population derived from a large data collection have yet to be available. The aim of this study was to create a reference database and to characterize the factors determining pulse wav...

The effects of tides on littoral marine habitats are so ubiquitous that shorelines are commonly described as 'intertidal', whereas waves are considered a secondary factor that simply modifies the intertidal habitat. However mean significant wave height exceeds tidal range at many locations worldwide. Here we construct a simple sinusoidal model of coastal water level based on both tidal range an...

In the past decades, many references have studied the mechanics of meandering damage for breakwater. However, up to the present time, no model has been proposed to compute the consequence of this kind of damage quantitatively. So, this paper tries to solve this problem by combining the expected sliding distance technique and the diffraction model. 1 Preface The meandering damage of breakwater i...

one of the cooling systems that has received considerable attentions in recent years is the adsorption chiller, which works based on the adsorption and desorption of a working fluid in a solid porous bed. different parameters such as fin height directly affect the bed heat and mass transfer processes, and therefore, the performance of the adsorption chillers. in the present study a numerical mo...

Thin liquid films driven up an inclined plane by temperature-induced surface tension gradients have been the focus of extensive mathematical and experimental research. Using the lubrication approximation, the motion of a thin liquid film is described by a single fourth-order partial differential equation (PDE) that models the evolution of the height of the film. Such films are now known to exhi...

The direct estimation of sea-state bias (SSB) from sea height residuals is extended with a parametric fitting process and a successive smoothing of the remaining residuals. This hybrid method essentially produces a nonparametric SSB model in the form of a smooth grid in a 2dimensional space determined by significant wave height and backscatter coefficient. The hybrid method allows a much higher...
