Numerical Model of Capillary Tubes: Enhanced Performance and Study of Non-Adiabatic Effects
(Purdue University, 2014)
Conference report
Restricted access - publisher's policyIn the present work a numerical model to simulate the thermal and fluid-dynamic phenomena inside non-adiabatic capillary tubes is presented. It consists of an improved version of the distributed model detailed in Ablanque ... -
Experimental investigation of inlet distortion effect on performance of a micro gas turbine
(2018-09-01)
Article
Open AccessAn experimental study has been carried out to determine how inlet total-pressure distortion affects the performance of a micro gas turbine. An inlet simulator is designed and developed to produce and measure distortion ... -
A time-average filtering technique to improve the efficiency of two-layer wall models for large eddy simulation in complex geometries
(Elsevier, 2019-06-30)
Article
Restricted access - publisher's policyTwo-Layer wall models have been recurrently studied since they represent a good physical model for Large Eddy Simulations with underresolved wall regions. Specifically, those based on the Reynolds Averaged Navier-Stokes ... -
A second-order time accurate semi-implicit method for fluid–structure interaction problems
(2019-04-01)
Article
Restricted access - publisher's policyThis paper is concerned with numerical solution of fluid-structure inter-action (FSI) problems involving an incompressible viscous flow and an elasticstructure. A semi-implicit partitioned method with second-order ... -
Numerical study of binary droplets collision in the main collision regimes
(2019-08-15)
Article
Restricted access - publisher's policyDirect numerical simulation of binary droplets collision is done using a conservative level-set method. The Navier-Stokes and level-set equations are solved using a finite-volume method on collocated grids. A novel lamella ... -
Numerical study of rising bubbles with path instability using conservative level-set and adaptive mesh refinement
(Elsevier, 2019-06-15)
Article
Restricted access - publisher's policyThis paper focuses on three-dimensional direct numerical simulations of rising bubbles in the wobbling regime, and the study of its dynamical behavior for Eötvös number 1 ≤ Eo ≤ 10 and Morton number 1e−11 ≤ M ≤ 1e−9. ... -
Numerical and experimental study of absorption of H2O vapor in wavy falling film of LiBr aqueous solution in vertical tubes and in presence of non-absorbables
(Elsevier, 2019-04-01)
Article
Restricted access - publisher's policyOne of the main reasons for the discrepancies between theoretical predictions of absorption phenomena made by mathematical models when they are compared against experimental results under real conditions, are the presence ... -

A Study of binary collision of GNF droplets using a conservative level-set method
(International Centre for Numerical Methods in Engineering (CIMNE), 2018)
Conference lecture
Restricted access - publisher's policyIn this study, numerical simulations of binary droplet collisions of two GNF droplets are carried out. Navier-Stokes equations are solved for fluid motion both inside and outside of the droplet using a conservative ... -

Direct numerical simulation of rising bubble with path instability
(2018)
Conference report
Restricted access - publisher's policyPresent research is focused on combining High- Performance Computing (HPC) and Direct Numerical Simulation (DNS) of two-phase flows, to study the dy- namic behavior of rising bubble whit path instabilities with moderate/high ... -
On the solution of the problem of a drop falling against a plane by using a level set-moving mesh-immersed boundary method
(WIT Press, 2018)
Article
Open AccessA coupled Conservative Level Set – Moving Mesh – Immersed Boundary method is formulated and validated against the three-dimensional gravity-driven falling drop problem. First, by employing Conservative Level-Set (CLS) ...
