A controversial rocket scientist in India earned his fourth retraction in October after an investigation at a physics journal found a core part of his work was “inaccurate and paradoxical.”
At issue is a highly technical concept developed by V.R. Sanal Kumar, a professor of aerospace engineering at Amity University in New Delhi. Other scientists have denounced the concept, which Kumar has dubbed “Sanal flow choking,” as “absolute nonsense,” as we reported in April.
The editors of AIP Advances appear to agree. An October 9 notice announcing the retraction of “A closed-form analytical model for predicting 3D boundary layer displacement thickness for the validation of viscous flow solvers” stated:
