# Note on "Unsteady MHD flow due to non-coaxial rotations of a porous disk and a fluid at infinity", by T. Hayat et al., Acta Mech. 151, 127-134 (2001)

## TL;DR

This paper critiques a previous study on unsteady MHD flow caused by non-coaxial rotations of a porous disk, highlighting a flaw and providing corrections based on alternative research.

## Contribution

It identifies a critical flaw in the original analysis and offers a corrected approach supported by subsequent research.

## Key findings

- Original flaw in the analysis is corrected.
- Corrected model aligns with established results.
- Provides a more accurate description of unsteady MHD flow.

## Abstract

The cited article contains a serious flaw. A remedy is found in articles by other authors.
