Heat Transfer Prediction for Methane in Regenerative Cooling Channels with Neural Networks [PDF]
, 2019 Methane is considered being a good choice as a propellant for future reusable launch systems. However, the heat transfer prediction for supercritical methane flowing in cooling channels of a regeneratively cooled combustion chamber is challenging. Because accurate heat transfer predictions are essential to design reliable and efficient cooling systems,

Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.

A Review of the Use of Chemical Stabilisation Methods for Lithium‐Ion Batteries
Battery Energy, EarlyView.The review reveals that while chemical stabilisation techniques for recycling EOL LIBs are widely used, many studies overlook safety risks, focusing on quick, low‐cost methods. Only a few studies address the associated hazards, highlighting the need for safer, well‐understood stabilisation processes in battery recycling. ABSTRACT The increasing amounts

Mathematical Modeling of Supercritical Fluid Extraction [PDF]
, 2010 The kinetics of supercritical fluid extraction of valuable substances from plants depends on both extract solubility in the solvent (or phase equilibrium between the matrix and the solvent) and mass transfer resistances, particularly the resistance inside vegetable material.

Comments on Van der Waals supercritical fluid: Exact formulas for special lines [J. Chem. Phys. 135, 084503 (2011)] [PDF]
arXiv, 2018 The equations for Widom lines for the supercritical van der Waals fluid were considered in the paper J. Chem. Phys. 135, 084503 (2011). But the equations for the speed of sound and its special Widom line were incorrect. The correct equations are obtained.

On Refinement of Several Physical Notions and Solution of the Problem of Fluids for Supercritical States [PDF]
arXiv, 2009 To solve the ancient problem of fluids, i.e., of states in which there is no difference between gas and liquid (the so-called supercritical states), it is necessary to abandon several "rules of the game", which are customary to physicists and to refine them by using rigorous mathematical theorems.
