This is the fifth blog of the Blog Series: Learning CFD in Aerospace Engineering.

Students can download their own 1-seat free student version.

For professors, teachers and researchers at a ridiculously low annual fee, the academic membership offers as many seats on as many cores as needed within the university department.


The interaction with FINE™/Open with OpenLabs™ does not end at the classroom for many of the students who attend the course of Professor Malashin. With the experience that they have gained from attending the course about meshing fundamentals, setting numerical parameters, post-processing results some of the students published articles on further work that they conducted with FINE™/Open with OpenLabs™. A few examples are shown below:

Khlupnov AI and Galaktionov A. Yu. made a comparative analysis on the unsteady aerodynamic flow around separated parts of launch vehicles. They considered cylindrical bodies with various degrees of curvature at supersonic speeds. In their research they compared the accuracy of their own solver against the FINE™/Open solver.

Yefremova M.Y., Krukov P.V. and Galaktionov A.Y., studied the aerodynamic characteristics of a spherical body with a channel at subsonic speeds. They studied the aerodynamic forces and pitching moments around the body at Reynolds number = 2.106 . The angles of attack in their study ranged from 0 to 90 degree. The flow patterns including the vortical structures were also an integral part of their investigation.

Figure 3: The flow pattern in the vicinity of the model at a 10 degree angle of attack [2]

 

Galaktinov A. Yu. and Antipova M.S. studied unsteady flow of free-falling bodies with FINE™/Open with OpenLabs™. Their investigation was based on the cylinders of varying degrees of curvature. During their investigation they compared the pitching-moment experienced by the cylinder for various radii of curvature for both subsonic and supersonic flow.
