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...
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...
Hypersonic flight involves a variety of complex flow phenomena that directly impact the aerothermodynamic loading of high-speed vehicles. The turbulence encountered during a typical flight trajectory influences and interacts with the shock waves on and around the surface of a vehicle and its propulsion system, affecting both aerodynamic and power p...
The interaction of turbulence with shock waves significantly modulates the frequency and amplitude of hydrodynamic fluctuations encountered by aerospace vehicles in low-altitude hypersonic flight. In these high-speed flows, intrinsic compressibility effects emerge together with high-enthalpy phenomena in the form of internal-energy excitation. The...
The Combustion Toolbox (CT) is a newly developed open-source thermochemical code designed to solve problems involving chemical equilibrium for both gas- and condensed-phase species. The kernel of the code is based on the theoretical framework set forth by NASA’s computer program CEA (Chemical Equilibrium with Applications) while incorporating new a...
The recent scientific and technological advancements have underscored the critical necessity for reliable, robust, and efficient numerical codes capable of predicting the chemical composition and properties of complex mixtures at chemical equilibrium. In response to this demand, this thesis presents the development and validation of a novel open-so...
The interaction between a weakly turbulent free stream of air and a hypersonic shock wave is investigated theoretically by using linear interaction analysis (LIA). The perturbation-free jump conditions across the shock are computed using Combustion Toolbox, an in-house thermochemical code capable of capturing high-temperature phenomena such as diss...
El interés por el desarrollo de armas hipersónicas está aumentando en los últimos años de forma notable. Las principales potencias mundiales han ensayado con éxito misiles hipersónicos de crucero, que, a diferencia de sus competidores directos (misiles balísticos o de crucero subsónico), ofrecen maniobrabilidad a velocidades que superan en un facto...
Se presenta un código termoquímico (en adelante Combustion Toolbox, CT) para el cálculo de problemas de combustión gaseosa con especies condensadas, choques reactivos y no reactivos, descomposición exotérmica de materiales energéticos y rendimiento teórico de cohetes. En particular, se exponen dos de los cuatro módulos que lo componen: CT-EXPLO y C...
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 to as SimEx, is presented and discussed. The classical correlations for the reference chemica...

Poster to be presented at The 1st Spanish Fluid Mechanics Conference (SFMC)
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).
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...
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...
