In a wide range of applications involving chemically reacting flows, thermochemical
calculations involving overall mass and energy balances with chemical equilibrium
are enough to estimate the overall performance of the system. This is often determined
by magnitudes such as the adiabatic flame temperature or the equilibrium
composition of the produ...
We propose a linear asymptotic theory to describe the propagation of planar detonation fronts through heterogeneous mixtures of reactive gases consisting of random fluctuations in the fuel mass fraction. The analysis starts with the derivation of the transfer functions that relate the upstream fuel-mass-fraction inhomogeneities with the burnt-gas p...
The interaction between a weakly turbulent free stream and a hypersonic shock wave is investigated theoretically by using linear interaction analysis (LIA). The formulation is developed in the limit in which the thickness of the thermochemical nonequilibrium region downstream of the shock, where relaxation toward vibrational and chemical equilibriu...
Slides of the talk "Development of an open-source thermochemical code. Fundamentals and application to shock turbulence interaction problems in the hypersonic regime", presented as part of the activities of the PhD Programme in Mechatronics Engineering of Universidad de Málaga (RD 99/2011).
The dynamic response of structural elements subjected to blast loading is a problem of growing interest in the field of defense and security. In this work, a novel computational tool for the rapid evaluation of the effects of explosions, hereafter referred as SimEx, is presented and discussed. The classical correlations for the reference chemical (...
Poster to be presented at The 1st Spanish Fluid Mechanics Conference (SFMC)
Para una gran variedad de dispositivos que involucran fenómenos de combustión, el cálculo de los estados en equilibrio químico es suficiente para definir parámetros que indiquen su rendimiento, como pueden ser la temperatura o la composición química de la mayoría de las especies químicas a la salida de una cámara de combustión en régimen estacionar...
La respuesta dinámica de una estructura sometida a cargas explosivas es un problema de gran importancia en el ámbito de la Defensa y Seguridad. Entre las medidas de protección pasiva más utilizadas en la actualidad destacan las barreras mitigadoras (T-Wall o HESCO® Bastion) cuyo objetivo es minimizar el impacto de la onda expansiva sobre el element...
Projects
Project (1)
The aim of this project is to develop an open-source thermochemical tool that can solve a wide range of combustion related problems.
Website: https://combustion-toolbox-website.readthedocs.io
Current Modules:
* CT-EQUIL: Thermochemical equilibrium module. Solve equilibrium composition given two function of states, e.g., enthalpy and pressure.
* CT-SD: Shock and detonation module. Compute pre-shock and post-shock states, e.g., incident, reflected, oblique, regular reflection.
* CT-ROCKET: Rocket propellant performance module. Obtain equilibrium composition at the injector, outlet of the chamber, throat, and exit points.
* CT-EXPLO: Thermochemical equilibrium module for High Energetic Materials (HEM). Solve thermochemical equilibrium of HEM [closed-source].
+ All the routines and computations are encapsulated in a more comprehensive and user-friendly GUI.
+ There is an early stage version of the code in Python (Combustion PyToolbox)
+ The code computes the equilibrium composition by minimization of the Gibbs–Helmholtz free energy by using Lagrange multipliers and allows gaseous and condensed species.
+ The code also computes equilibrium properties of ideal plasmas, i.e., no coulombic interactions are considered.
+ It employs NASA’s 9-coefficient polynomial fits to evaluate the thermodynamic properties.
