Over-the-needle trans-septal access using the cryoballoon delivery sheath and dilator in atrial fibrillation ablation Vrije Universiteit Brussel
BACKGROUND: In the setting of second-generation cryoballoon (CB2) ablation, left atrial (LA) access is generally achieved using a standard sheath (SS) that is exchanged for the 15Fr cryoballoon delivery sheath (CBS) and dilator over a long wire (CBS over-the-wire technique, CBS-W). Our objective was to evaluate the direct use of the CBS to gain LA access, by advancing the latter over the trans-septal needle (CBS over-the-needle technique, ...
Laparoscopic versus open thermal ablation of colorectal liver metastases : a propensity score-based analysis of local control of the ablated tumors Universiteit Gent
Material response characterization of a low-density carbon composite ablator in high-enthalpy plasma flows Vrije Universiteit Brussel
materials for the thermal protection system in order to shield the spacecraft from the severe heating during
reentry. In this paper, we present the results of an elaborate test campaign on a lightweight carbon composite
ablator with the aim of defining a procedure for material response characterization in a 1.2-MW ...
Competitive kinetic model for the pyrolysis of the Phenolic Impregnated Carbon Ablator Vrije Universiteit Brussel
Carbon/phenolic ablators are successfully used as thermal protection material for spacecraft. Nevertheless, their complex thermal degradation is not yet fully understood, and current pyrolysis models do not reproduce important features of available experimental results. Accurate and robust thermal degradation models are required to optimize design margin policy. We investigate whether the competitive kinetic schemes commonly used to model ...
A high heating rate pyrolysis model for the Phenolic Impregnated Carbon Ablator (PICA) based on mass spectroscopy experiments Vrije Universiteit Brussel
A novel model for the pyrolysis of the Phenolic Impregnated Carbon Ablator (PICA) at high heating rate is developed and calibrated based on high fidelity thermal decomposition experiments. The calibration relies on accurate quantification of pyrolysis gases obtained from mass spectroscopy analysis during thermal decomposition at fast heating rates simulating flight conditions. Model calibration is achieved by coupling the Porous material ...

Experimental investigation of the material response of carbon composite ablators in the VKI Plasmatron facility Vrije Universiteit Brussel
Two di fferent test gases were used, air and nitrogen, for heat flux levels ranging from 0.85MW/m^2 to 4.5MW/m^2.
A comprehensive experimental setup was developed with ...
