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...

Laboratory Response Network (LRN) laboratories help protect populations from biological and chemical public health threats. We examined the role of LRN biological laboratories in enhancing capacity to detect and respond to public health infectious disease emergencies in South Korea. The model for responding to infectious disease emergencies leverages standardized laboratory testing procedures, ...

To improve the calculation of the flow properties of an aerospike nozzle, different turbulence models were investigated in this study. The primary shape of the nozzle plug is determined through utilizing an approximate method. The flow field is, then, simulated using the Navier-Stokes equations for compressible flows. The commercial computational fluid dynamics code Fluent is used to simulate t...

Classic cadherins are calcium dependent homophilic cell adhesion molecules that play a key role in developmental processes such as morphogenesis, compartmentalization and maintenance of a tissue. They also play important roles in development and function of the nervous system. Although classic cadherins have been shown to be involved in the migration of non-neuronal cells, little is known about...

There are many approaches to determine the sound propagated from turbulent flows.  In hybrid methods, the turbulent noise source field is computed or modeled separately from the far-field calculations.  To have an initial and quick estimation of the sound propagation, less computationally intensive methods can be developed using stochastic models of the turbulent fluctuations.   In this paper, ...

In recent years, the use of offshore wind turbines has been considered on the agenda of the countries which have a significant maritime boundary due to more speed and stability of wind at sea. The aim of this study is to investigate the effect of wind turbulence on the aero-hydrodynamic behavior of offshore wind turbines with a monopile platform. Since in the sea, the wind turbine structures ar...

There are several reconfiguring models of parallel computation that are considered in the published literature, depending on their switching capabilities. Three of the more popular ones are the Horizontal-Vertical Reconfigurable Mesh (HV-RN model) [LM89a, LM89b, ML89], the Linear Reconfigurable Mesh (LRN model) [MPRS87, BPRS91], and the General Reconfigurable Mesh (RN model) [Wan91, Sch91]. Can...

Estimating the oil-water temperatures in flowlines is challenging especially deepwater and ultra-deepwater offshore applications where issues of flow assurance dramatic heat transfer are likely to occur due temperature difference between fluids surroundings. Heat analysis very important for prediction prevention deposits oil water flowlines, which could impede give rise huge financial losses. T...

In the following paper, the effects of a choked jet exhausted from the base of a non-lifting body on its total and base drags at sub-sonic and transonic regimes has been numerically investigated. Having surveyed the results of some turbulence models and after comparing with experimental results, an appropriate turbulence model i.e. SST K-?, has been chosen and this model has been used in the su...
