Analysis of quasi-hybrid solid rocket booster concepts for advanced earth-to-orbit vehicles [PDF]
A study was conducted to assess the feasibility of quasi-hybrid solid rocket boosters for advanced Earth-to-orbit vehicles. Thermochemical calculations were conducted to determine the effect of liquid hydrogen addition, solids composition change plus ...

Cold cathode gauge experiment (ALSEP) [PDF]
, 1974 Cold cathode ionization gages were left on the lunar surface as part of ALSEP (Apollo Lunar Surface Experiment Package) on Apollo missions 12, 14, and 15. An instrument prepared for Apollo 13 did not reach the surface because of the abort of that mission.

High power ultrasound combined with supercritical carbon dioxide for the drying and microbial inactivation of coriander [PDF]
, 2018 This work explores the use of supercritical carbon dioxide (scCO2) drying in combination with High Power Ultrasound (HPU) to enhance both the dehydration efficiency and the microbial inactivation on coriander leaves.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...

PWR-depressurization and its hydraulic analogy [PDF]
Nuclear Engineering and Design, 1978 Abstract The aim of this work is to provide an experimental verification of codes to be used for numerical simulation of the depressurization process in a pressurized water reactor (PWR) in case of a hypothetical blowdown accident. Here, the downcomer of a PWR is approximately treated as a two-dimensional plane region (unwrapped).

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

Experimental study of high pressure phase equilibrium of (CO2 + NO2/N2O4) mixtures [PDF]
, 2011 Experimental bubble pressure, as well as liquid density of (CO2 + NO2/N2O4) mixtures are reported at temperatures ranging from (298 to 328.45) K. Experiments were carried out using a SITEC high-pressure variable volume cell.

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...
