Supercritical Calorimetry: An Emerging Field

CHIMIA, 2002
Calorimetry (adiabatic, isothermal, differential, oscillating or acoustic) is generally based on heat-flow measurements of the studied system. Most of its applications are dedicated to kinetic-parameter determination, safety studies and process ...

Numerical Comparison of Thermalhydraulic Aspects of Supercritical Carbon Dioxide and Subcritical Water-Based Natural Circulation Loop

Nuclear Engineering and Technology, 2017
Application of the supercritical condition in reactor core cooling needs to be properly justified based on the extreme level of parameters involved. Therefore, a numerical study is presented to compare the thermalhydraulic performance of supercritical ...

A first principles method to determine speciation of carbonates in supercritical water

Nature Communications, 2020
The determination of the speciation of ions and molecules in supercritical aqueous fluids under pressure is key to understanding their mass transport in the Earth’s interior.

Dimensionless scaling of heat-release-induced planar shock waves in near-critical CO2

, 2017
We performed highly resolved one-dimensional fully compressible Navier-Stokes simulations of heat-release-induced compression waves in near-critical CO2. The computational setup, inspired by the experimental setup of Miura et al., Phys. Rev.

Time-frequency analysis of ship wave patterns in shallow water: modelling and experiments

, 2018
A spectrogram of a ship wake is a heat map that visualises the time-dependent frequency spectrum of surface height measurements taken at a single point as the ship travels by.

Determination of paclitaxel anticancer drug solubility in supercritical CO2: Thermodynamics modeling and machine learning approach

Case Studies in Thermal Engineering
To facilitate the effective design of supercritical fluid (SCF) processes aimed at micro- or nanosizing solid pharmaceuticals, obtaining solubility data in environmentally friendly solvents such as pressurized carbon dioxide (CO2) is essential ...
