CO2-Driven diffusiophoresis and water cleaning: similarity solutions for predicting the exclusion zone in a channel flow

Mrudhula Baskaran

We investigate experimentally and theoretically diffusiophoretic separation of negatively charged particles in a rectangular channel flow, driven by CO2 dissolution from one side-wall. Since the negatively charged particles create an exclusion zone near th ...

A plane‐strain hydraulic fracture driven by a shear‐thinning Carreau fluid

Brice Tanguy Alphonse Lecampion, Lucas Pereira

We study the propagation of a plane‐strain hydraulic fracture driven by a shear thinning fluid following a Carreau rheology. We restrict to the impermeable medium case and quantify in details the impact on fracture growth of the shear‐thinning properties o ...

Shape optimisation of technical devices via gradient descent using convolutional neural network proxies

Pascal Fua, François Fleuret, Pierre Bruno Baqué

The present invention generally relates to a method, a system and a computer program for shape optimisation of a technical device adapted to be exposed to a fluid flowing around a contour of said device with respect to its fluid dynamic parameters. In orde ...

Dynamic behavior of rock during its post failure stage in SHPB tests

Yang Zou, Yang Zhao, Xin Cai

In order to investigate the micro-process and inner mechanism of rock failure under impact loading, the laboratory tests were carried out on an improved split Hopkinson pressure bar (SHPB) system with synchronized measurement devices including a high-speed ...

Katabatic Flow: A Closed-Form Solution with Spatially-Varying Eddy Diffusivities

Jiannong Fang, Peter Monkewitz, Marc Parlange, Marco Giovanni Giometto

The Nieuwstadt closed-form solution for the stationary Ekman layer is generalized for katabatic flows within the conceptual framework of the Prandtl model. The proposed solution is valid for spatially-varying eddy viscosity and diffusivity (O'Brien type) a ...

MATHICSE Technical Report : Large Eddy simulations for blood fluid-dynamics in real stenotic carotids

Alfio Quarteroni, Christian Vergara

In this paper, we consider Large Eddy Simulations (LES) for human stenotic carotids in presence of atheromasic plaque. It is well known that in such a pathological condition, transitional effects to turbulence may occur, with relevant clinical implications ...

Large Scale Dynamic Models of Metabolism as a Tool for Analysis and Design of Metabolic Engineering and Synthetic Biology Strategies

Vassily Hatzimanikatis, Ljubisa Miskovic, Georgios Fengos

Large-scale dynamic models of metabolism remain an overarching ambition of efforts that aim to analyze and explain complex behavior of living entities. However, intrinsic nonlinearity of dynamics of living organisms and structural and quantitative uncertai ...

Flow adjustment in a finite size wind farm in a neutral ABL

Varun Sharma, Marc Parlange, Marc Calaf Bracons

It is now well-recognized that in the presence of an asymptotically large wind farm, the ABL adjusts to this ‘enhanced’ roughness to form a fully developed ‘wind turbine array boundary layer’ (WTABL), where the driving force of the ABL is in balance with t ...
