Volume 6, Issue 2 , September 2022, , Pages 23-39

https://doi.org/10.22034/jtae.2022.302257.1192

Abstract
  This paper uses the dissipative particle dynamic method to simulate the flow around a micro-airfoil. Due to the common problem in applying boundary conditions and the lack of aerodynamic study of objects in this molecular method, we decided to study this field. In this study, periodic boundary conditions ...  Read More

Ramin Zakeri; Rokhshaad Dashti gohari; Esmaeil Yadollahi

Volume 3, Issue 2 , September 2019, , Pages 1-9

Abstract
  In this paper, the dissipative particle dynamic method is used to simulate the electrosmotic micro pump as the main part of a spatial-chemical propulsion system. In this simulation, the micro-pump is driven by the principle of  electrosmotic flow.Furthermore,the effective parameters, such as channel ...  Read More
