Etude expérimentale du fonctionnment cavitant d'une pompe lors de séquences de démarrage rapide

Autor: Duplaa, Sébastien

Résumé : Sur les moteurs des lanceurs spatiaux comme Ariane V, le démarrage des turbopompes est effectué en quelques secondes. Par conséquent, ces pompes atteignent leurs conditions de fonctionnement nominales après seulement quelques rotations

Exergy analysis of unsteady flow around an adiabatic cylinder in vortex shedding condition

Autor: Ruscio, Juan Pablo, Duplaa, Sébastien, Aguirre, Miguel Angel, Binder, Nicolas

This paper shows the application of the aerodynamics exergy analysis preliminary formulation developed for unsteady flows for adiabatic and fixed bodies under low subsonic flow conditions (no shock-waves). The numerical implementation for URANS CFD c

Epsilon v3: exergy-based aerodynamic analysis tool for cfd and wtt data

Autor: Aguirre, Miguel Angel, Duplaa, Sébastien

In 2020, ISAE-SUPAERO has released the first version of Epsilon: an open source tool for the aerodynamic analysis of CFD data with Paraview [1]. Several methods were available: near-field, far-field, Lamb vector and exergy. In the original release, C

Exergy analysis of a delta wing: a challenging test case

Autor: Aguirre, Miguel Angel, Duplaa, Sébastien, Caron, Pablo Alfredo

The aerodynamic analysis by the exergy method is a powerful approach which allows establishing the theoretical limits of the aerodynamic performance of a given body, based on an aero-thermodynamic approach. The most used formulation is the Arntz’s

A better assessment of the recoverable energy behind a body by the exergy method

Autor: Aguirre, Miguel Angel, Duplaa, Sébastien, Carbonneau, Xavier, Turnbull, Andrew, Arntz, Aurélien

The aerodynamic analysis by the exergy method is reviewed. The existing formulations are analyzed for an external flow test case (NACA 0012 airfoil). This lead to the detection of some discrepancies between the CFD-based formulation and the wind-tunn

Epsilon: An Open Source Tool for Exergy-Based Aerodynamic Analysis

Autor: Aguirre, Miguel Angel, Duplaa, Sébastien

This paper presents the open source code called “Epsilon”. It is a tool suited for the aerodynamic analysis of CFD and wind tunnel data by using the exergy method. Other methods are also provided (near-field, far-field, Lamb vector). The architec

Vortex Exergy Prediction

Autor: Aguirre, Miguel Angel, Duplaa, Sébastien, Carbonneau, Xavier

This paper aims to provide a prediction method for the transverse exergy of the wing’s trailing vortices. It relates the transverse exergy at each point of the entire downstream survey plane to the vorticity inside the wake. This allows reducing th
