Energy-preserving stable computations of high-pressure supercritical fluids turbulence
(2022)
Conference report
Open AccessHigh-fidelity computations of turbulent flows at high-pressure supercritical fluid conditions present significant challenges. Besides the inherent broadband nature of the flow, the rapid variation of thermophysical properties ... -
Study of the conservation properties in two-way coupled dispersed multiphase flows using finite volume methods
(Institute of Physics (IOP), 2021)
Conference lecture
Open AccessIn order to simulate dispersed multiphase flows, the coupling level must be determined according to the volume fraction in the system. The volume fraction is the ratio of the total volume of the dispersed phases over the ... -
DNS of Mass Transfer in Bi-dispersed Bubble Swarms
(2022)
Conference report
Restricted access - publisher's policyThis work presents Direct Numerical Simulation of mass transfer in a bi-dispersed bubble swarm at high Reynolds number, by using a multiple marker level-set method. Transport equations are discretized by the finite-volume ... -

Open AccessThe present work describes the Multi-frequency Automotive GNSS Integrated Cost-effective Antenna (MAGICA) project and the first results. This is a two years project that started in August 2020 under the sponsorship of the ... -
Numerical Investigation on fluid flow of protruding branching duct in a dividing junction of a minichannel heat exchanger
(2021)
Conference report
Open AccessThis study focuses on investigating the effect of protruding branching duct on laminar fluid field in 90¿ dividing pipe junction of mini heat exchanger. The ducts under study, main and branch side, are of minichannel scale ... -
DNS of unequal size droplets collision using a moving-mesh/level-set method
(Springer, 2019)
Conference report
Restricted access - publisher's policyThe dynamics of binary droplets collision is of huge importance in different fields, from multiphase reactors (Dudukovic et al in Chem Eng Sci 54:1975–1995, 1999 [11]), raindrop formation, ink-jet printing, spray combustion, ... -
DNS of Drag-Force and Reactive Mass Transfer in Gravity-Driven Bubbly Flows
(Springer, 2019)
Conference report
Restricted access - publisher's policyMass transfer processes in bubbly flows are relevant in both nature and industry. Multiple examples arise from the so-called unit operations of the chemical engineering, where bubble columns are used for separation processes, ... -
A GPU Accelerated Framework for Partitioned Solution of Fluid-Structure Interaction Problems
(2021)
Conference report
Open AccessWe present a GPU-accelerated solver for the partitioned solution of fluid-structure interaction (FSI) problems. Independent scalable fluid and structure solvers are coupled by a library which handles the inter-code data ... -
Paving the (right) way for DNS and LES on unstructured grids: (fully) conservative collocated/staggered discretizations
(2021)
Conference report
Restricted access - publisher's policyThe essence of turbulence are the smallest scales of motion. They result from a subtle balance between convective transport and diffusive dissipation. Mathematically, these terms are governed by two differential operators ... -
Symmetry-preserving discretization of Navier-Stokes on unstructured grids: collocated vs staggered
(2021)
Conference report
Open AccessThe essence of turbulence are the smallest scales of motion. They result from a subtle balance between convective transport and diffusive dissipation. Mathematically, these terms are governed by two differential operators ... -
