Assessment of 3D-RANS models for the simulation of topographically forced shallow flows

Journal of Hydrology and Hydromechanics, 2016
In this work the performance of Reynolds Averaged Navier-Stokes (RANS) simulations to predict the flow structure developed by the presence of a sidewall obstacle in a uniform open-channel shallow flow is discussed. The tested geometry was selected due to

LES-based investigation on external heat transfer characteristics of turbine blades for gas turbine (About the effect of turbine blades configuration)

Nihon Kikai Gakkai ronbunshu, 2015
Accurate prediction of external heat transfer around a turbine is important in high efficiency gas turbine development. Experimental and computational fluid dynamics studies were performed to investigate the heat transfer characteristics around two types

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Numerical Modelling of Wind Flow In Street Canyon Between High-Rise Buildings with Angle of Attack Modifications

Media Komunikasi Teknik Sipil, 2023
In fluid dynamics analysis, one of the things to do is to perform numerical modeling validated on the results of experimentation. In numerical modeling of wind flow there are several forms of modeling used including RANS, LES, DNS, etc.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Experimental and numerical assessment of the effect of speed and loading conditions on the nominal wake of a containership

Brodogradnja
An important aspect of the design of the propeller is the determination of the nominal wake. In this study, the nominal wake of a Post Panamax containership is determined numerically and experimentally at different speeds and loading conditions.

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

A RANS Modelling Approach for Predicting Powering Performance of Ships in Waves [PDF]

, 2013
In this paper, a modelling technique for simulating selfpropelled ships in waves is presented. The flow is modelledusing a RANS solver coupled with an actuator diskmodel for the propeller.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
