Bow Shock Clustering in Particle-laden Wetted Cylinder Flow
(Peer reviewed; Journal article, 2020)The inhomogeneous distributions of inertial particles in the unsteady flow around a wetted circular cylinder at Re=100 were investigated in one-way coupled three-dimensional numerical simulations. The Kármán vortex cells ... -
Clusters and coherent voids in particle-laden wake flow
(Peer reviewed; Journal article, 2021)Inertial point particles suspended in a two-dimensional unsteady circular cylinder flow at Re = 100 are studied by one-way coupled three-dimensional numerical simulations. The striking clustering pattern in the near-wake ... -
Comparison of kinetic theory evaporation models for liquid thin-films
(Journal article; Peer reviewed, 2019)We summarize the background and derivation of non-equilibrium evaporation models from kinetic theory, and demonstrate how they may be applied in the context of fluid mechanics and heat transfer problems. We find that the ... -
Depressurization of in a pipe: Effect of initial state on non-equilibrium two-phase flow
(Peer reviewed; Journal article, 2023)It is key in several industrial applications to accurately describe rapid depressurization of liquid and dense phase states. Examples include refrigeration systems, nuclear reactor cooling and capture and storage (CCS). ... -
Dynamics of disk-like particles in turbulent vertical channel flow
(Journal article; Peer reviewed, 2017)The dynamical behavior of inertial disk-like particles in turbulent vertical channel flow is investigated by an Eulerian–Lagrangian point-particle approach. Gravity effects on distribution, translation, rotation and ... -
The effect of Stefan flow on Nusselt number and drag coefficient of spherical particles in non-isothermal gas flow
(Peer reviewed; Journal article, 2021)A Stefan flow can be generated during a phase change or reactions of a particle immersed in a fluid. This study investigates the effect of Stefan flow on the exchange of momentum (drag coefficient (CD)) and heat transfer ... -
Experiments and modelling of choked flow of CO2 in orifices and nozzles
(Peer reviewed; Journal article, 2022)In order to accelerate the deployment of capture and storage (CCS), engineers need experimentally validated models, among other things, to predict the mass flow rate in process equipment and flow restrictions like valves, ... -
A flashing flow model for the rapid depressurization of CO2 in a pipe accounting for bubble nucleation and growth
(Peer reviewed; Journal article, 2023)Flashing flow is encountered in many industrial systems involving nozzles, valves and decompression of vessels and pipes. In the context of CO2 capture and storage (CCS), the design of safe and efficient CO2 transportation ... -
Inclination dependence of planar film boiling stability
(Journal article; Peer reviewed, 2018)Understanding the dynamics of film boiling is crucial for predicting its heat transfer properties. Besides the complete breakdown of film boiling (Leidenfrost point), the most prominent transition is the change from a ... -
Inclined film boiling: Film stability and heat transfer
(Journal article; Peer reviewed, 2018)An inertially modified long-wave model is used to analyze the stability of inclined saturated film boiling. By performing quasi-parallel linear stability analysis on this model and combining the result with a heat-transfer ... -
Influence of surfactants on the electrohydrodynamic stretching of water drops in oil
(Journal article; Peer reviewed, 2017)In this paper we present experimental and numerical studies of the electrohydrodynamic stretching of a sub-millimetre-sized salt water drop, immersed in oil with added non-ionic surfactant, and subjected to a suddenly ... -
On interface transfer terms in two-fluid models
(Journal article; Peer reviewed, 2012)In this note we consider two-fluid models based on the usual formulations for conservation of mass, total momentum and total energy. We present some potentially useful general relationships between the interface exchange ... -
Particle segregation in turbulent Couette-Poiseuille flow with vanishing wall shear
(Journal article, 2017)Inertial particles dispersed in wall-bounded flows in pipes and channels are known to accumulate close to the walls. The segregation ability depends greatly on the inertia-selection effects of the near-wall quasi-coherent ... -
The effect of Stefan flow on the drag coefficient of spherical particles in a gas flow
(Journal article; Peer reviewed, 2019)Particle laden flows with reactive particles are common in industrial applications. Chemical reactions inside the particle can generate a Stefan flow that affects heat, mass and momentum transfer between the particle and ... -
Thermal two-phase flow with a phase-field method
(Journal article; Peer reviewed, 2018)Phase field methods have become of great interest for the simulation of droplet and bubble dynamics, moving free interfaces and more recently phase change phenomena. One example is the Navier–Stokes–Korteweg (NSK) equations. ... -
Transition between coalescence and bouncing of droplets on a deep liquid pool
(Journal article; Peer reviewed, 2011)This study focused on the bouncing of sub-millimetric droplets (below 0.7 mm) of three different fluids, distilled water, technical ethanol and 1-propanol on a deep liquid pool of the same fluids. Four different flow regimes ...
