Thermodynamic properties of L-menthol in crystalline and gaseous states

open access: yesТонкие химические технологии, 2020
Objectives. Menthol causes a cooling sensation and reduces the nerve activity when it is applied locally, ingested, or inhaled. This feature explains its extensive use as both an aromatizer and a flavoring agent in food manufacturing, tobacco industry ...

Structure-property relationships in alkoxy substituted benzoates from experimental and computational thermochemistry

open access: yesChemical Thermodynamics and Thermal Analysis, 2023
The energetics of formation and the phase transitions for isomeric methyl and ethyl methoxy‑benzoates were studied. The vapour pressures of methyl 2‑methoxy-benzoate and methyl 4‑methoxy-benzoate were measured by transpiration method.

Fast computation of multi-scale combustion systems [PDF]

open access: yes, 2011
In the present work, we illustrate the process of constructing a simplified model for complex multi-scale combustion systems. To this end, reduced models of homogeneous ideal gas mixtures of methane and air are first obtained by the novel Relaxation ...

Accounting for convective effects in zero-Mach-number thermoacoustic models [PDF]

open access: yes, 2014
This paper presents a methodology to account for some mean-flow effects on thermo-acoustic instabilities when using the zero-Mach-number assumption. It is shown that when a computational domain is represented under the M=0 assumption, a nonzero-Mach ...
