TLDR
The theory of fluid mechanics can be profitably applied to chemistry by simply noting that many fluids are substances as discussed by the authors, and some of the most valuable parts of this theory may, for some purposes, also be regarded as a part of elementary physics completely independent of thermodynamics.Abstract:
The theory of fluid mechanics can be profitably applied to chemistry by simply noting that many fluids are substances. Certain equations of fluid mechanics then become the counterparts of equations in the theory of the chemical thermodynamics of systems at constant temperature. Consequently, some of the most valuable parts of this theory may, for some purposes, also be regarded as a part of elementary physics completely independent of thermodynamics.read more

Material and Energy Efficiency Analysis of Low Pressure Chemical Vapor Deposition of TiO2 Film
TL;DR: In this paper, the material and energy consumption of LPCVD of TiO2 thin-film process were analyzed under five different reaction conditions (623K, 500 Pa, 673K, 400 Pa; 673k, 300 Pa), and the results showed that the energy efficiency is low (less 0.1% in each condition) and increases with decreasing temperature and increasing pressure.

A model for the mass transfer coefficient in rotating packed bed
TL;DR: Based on the locus of ink on the well-rotating disc, a model for the mean residence time of liquid in a rotating packed bed, t = ϕ′ e (ctg(α2/2) − ctg (α1/2))ωu), is proposed in this article.

A New Model to Predict Average Pressure Difference of Liquid Droplet and Its Application in Gas Well
Haiquan Zhong,Jiao Tan,Chi Zhang +2 more
TL;DR: In this paper, a new model is established to predict the average differential pressure of droplets in high velocity gas streams in gas wells, and compared with the original one, the improved model showed that it is necessary to consider the adaptability, because the models have significant discrepancy in results, and different suitability for different well conditions.
