The precipitation response to sea surface temperature (SST) gradients associated with the Gulf Stream is investigated using an atmospheric general circulation model. Forced by observed SST, the model simulates a narrow band of precipitation, surface convergence, and evaporation that closely follows the Gulf Stream, much like satellite observations. Such a Gulf Stream rainband disappears in the ...

This paper presents a time-domain model of a MV/LV bidirectional solid state transformer (SST). A multilevel converter configuration of the SST MV side is obtained by cascading a single-phase cell made of the series connection of an H bridge and a dual active bridge (dc-dc converter); the aim is to configure a realistic SST design suitable for MV levels. A three-phase four-wire converter has be...

The skewness and kurtosis of daily sea surface temperature (SST) variations are found to be strongly linked at most locations around the globe in a new high-resolution observational dataset, and are analyzed in terms of a simple stochastically forced mixed layer ocean model. The predictions of the analytic theory are in remarkably good agreement with observations, strongly suggesting that a uni...

The frequent switching of pump mode and turbine the leads to transient phenomena. To ensure safe stable operation unit, a detailed study on exhaust pressurization process when unit switches from has been carried out. Based Shear Stress Transfer model (SST) k–ω turbulent model, numerical simulations are processed both in steady unsteady state. visualization results gas–liquid two phases distribu...

Abstract Vertical axis wind turbine (VAWT) array design requires adequate modelling of the wakes to model flow throughout and, therefore, power output turbines in array. This paper investigates how accurately different turbulence models using 2D computational fluid dynamics (CFD) simulations can estimate near and far VAWTs determine an approach towards accurate for design. Three experiments fro...

Abstract This study investigates what forms the spatial pattern of amplitude changes in tropical intraseasonal and interannual variability—represented by two most important variables, precipitation (Δ P ′) circulation ω ′)—under global warming, based on 24 models from phase 5 Coupled Model Intercomparison Project (CMIP5). Diagnostic analyses reveal that moisture budget thermodynamic energy equa...

Current research focuses on predicting and mitigating the impacts of high hydraulic loadings on centralized wastewater treatment plants (WWTPs) under wet-weather conditions. The maximum permissible inflow to WWTPs depends not only on the settleability of activated sludge in secondary settling tanks (SSTs) but also on the hydraulic behaviour of SSTs. The present study investigates the impacts of...

In this paper we introduce some search strategies under the general term SST (Search Strategy for Tutoring) intended to be used in tutoring games. Contrary to principles of tutoring game-playing programs stated elsewhere, we argue that tutoring systems not necessarily should interrupt games or provide explicit advice. In addition, unlike earlier tutoring strategies , SST does not depend on a pr...

Shock wave/boundary layer interaction (SWBLI) is a highly critical problem that occurs in aircraft transonic or supersonic flow. This study performed CFD analysis of the ramp flow freestream Mach number 2.79. To secure reliability analysis, adaptive mesh refinement using gradient p sensor was used. Through this, grid sufficient resolution obtained for region shock wave, expansion and separation...
