Cfd investigation of spacer-filled channels for membrane distillation [PDF]

open access: yes, 2019
The membrane distillation (MD) process for water desalination is affected by temperature polarization, which reduces the driving force and the efficiency of the process. To counteract this phenomenon, spacer-filled channels are used, which enhance mixing

Comparison of Sweepgas and Vacuum Membrane Distillation as In-Situ Separation of Ethanol from Aqueous Solutions

open access: yesChemical Engineering Transactions, 2014
The rising oil prices, as well as the desire to reduce the environmental impact of fossil fuels, increases the interest in fuels from renewable raw materials. Bioethanol production via starch fermentation is state of the art.

Phase drift and noise suppression method based on SEE-SGMD-PCC in a distributed acoustic sensor

open access: yesOptics Express, 2023
The problems of laser source frequency drift (LSFD) and phase noise in distributed acoustic sensor (DAS) make it difficult to recover the true vibration phase curve, which limits its application scope in the field of seismic exploration. In order to suppress the influence of phase noise and phase drift on the phase signal and improve the signal-to ...
