A bio-chemo-hydro-mechanical model for microbially induced calcite precipitation in soils

Microbial Induced Calcite Precipitation (MICP) is an innovative technique for soil grouting involving a bacterial reactive grout. A comprehensive research work is carried out to better understand and consequently describe the phenomenon of multispecies rea ...

The role of turbulence in the hydraulic environment of benthic invertebrates

Koen Blanckaert, Ana Margarida Da Costa Ricardo

The role of turbulence in the dislodgment of benthic stream invertebrates from the riverbed was investigated experimentally in a laboratory flume. For the first time, technological advances allowed measuring the spatio-temporal patterns of turbulent flow a ...

Numerical Simulation of Sailing Boats: Dynamics, FSI, and Shape Optimization

Alfio Quarteroni, Gianluigi Rozza, Nicola Parolini, Matteo Lombardi

The numerical simulation of free-surface flows around sailing boats is a complex topic that addresses multiple mathematical tasks: the correct study of the flow field around a rigid hull, the numerical simulation of the hull dynamics, the deformation of th ...

Stability analysis and control of the flow in a symmetric channel with a sudden expansion

Andrea Fani

The laminar flow in two-dimensional diffusers may produce either symmetric or nonsymmetric steady solutions, depending on the value of the Reynolds number as compared with some critical value. The stability properties of the flow are studied in the context ...

The onset of dynamic stall revisited

Karen Ann J Mulleners

Dynamic stall on a helicopter rotor blade comprises a series of complex aerodynamic phenomena in response to the unsteady change of the blade's angle of attack. It is accompanied by a lift overshoot and delayed massive flow separation with respect to stati ...

Hub vortex helical instability as the origin of wake meandering in the lee of a model wind-turbine

Fernando Porté Agel, François Gallaire, Giacomo Valerio Iungo, Francesco Viola

Wind tunnel measurements were performed for the wake produced by a three-bladed wind turbine immersed in uniform flow. These tests show the presence of a vorticity structure in the near wake region mainly oriented along the streamwise direction, which is d ...

Experimental Investigation of the Aeroelastic Stability of an Annular Compressor Cascade at Reverse Flow Conditions

Virginie Anne Chenaux

Compressor surge events are unsafe operating regimes yielding highly unsteady flow fields in which complex aeroelastic phenomena occur. If the blade flutter and forced response behaviour (i.e. aeroelastic stability) can be predicted reliably for normal flo ...

Solute transport in partially-saturated deformable porous media: Application to a landfill clay liner

David Andrew Barry

Based on the one-dimensional Biot consolidation equations, this paper developed an advection-diffusion equation that incorporates saturation, compressibility of the pore fluid and longitudinal dispersivity of the solute transport in an unsaturated, deformi ...

A theory for the streamwise turbulent fluctuations in high Reynolds number pipe flow

A new theory for the streamwise turbulent fluctuations in fully developed pipe flow is proposed. The theory extends the similarities between the mean flow and the streamwise turbulence fluctuations, as observed in experimental high Reynolds number data, to ...

Heat transfer enhancement in a straight channel via a rotationally oscillating adiabatic cylinder

Mohsen Cheraghi

Heat convection from the uniformly heated walls of a straight channel in presence of a rotationally oscillating cylinder (ROC) is simulated at Re = 100. Heat transfer enhancement due to vortex shedding from the ROC is investigated. Systematic studies are p ...
