Comments on “Influence of chemical reaction and viscous dissipation on MHD mixed convection flow” by K. Das [JMST 28 (5) (2014) 1881~1885] and “Cu-water nanofluid flow and heat transfer over a shrinking sheet” by K. Das [JMST 28 (12) 5089~5094]

Abstract

In this letter, we submit our comment on the following recently published papers by Kalidas Das: (1) “Influence of chemical reaction and viscous dissipation on MHD mixed convection flow,” Journal of Mechanical Science and Technology 28 (5) (2014) 1881-1885; and (2) “Cu-water nanofluid flow and heat transfer over a shrinking sheet,” Journal of Mechanical Science and Technology 28 (12) (2014) 5089-5094. The authors attempt to present the similarity solutions in both papers. We comment that the similarity transformations considered in Refs. [1, 2] are incorrect. Thus, the results presented by Kalidas Das lead to invalid conclusions.

Additional information

P. M. Patil obtained his bachelor of science (1982), master of science (1984), and doctor of philosophy (1996) degrees from Karnatak University, Dharwad, India. Dr. Patil began his teaching career at BLDEA’s BHS Arts and TGP Science College, Jamakhandi - 587 302 in 1986, where he served until 1993. Later, Dr. Patil moved to JSS’s Banashankari Arts, Commerce and Shanti Kumar Gubbi Science College, Vidyagiri, Dharwad 580 004, where he served until October 2013. At present, Dr. Patil works as a professor in the P. G. Department of Mathematics, Karnatak University, Dharwad-580 003. Dr. Patil has worked as a visiting scientist from March 1998 to June 1998 at UGC-DSA Centre in Fluid Mechanics, Department of Mathematics, Bangalore University, Bangalore-560 001. Dr. Patil was awarded with the prestigious Commonwealth Academic Fellowship (2011-2012) tenable at Department of Mechanical Engineering, University of Bath, United Kingdom. Dr. Patil’s research work is interdisciplinary in nature and covers various aspects of convective heat and mass transfer and computational fluid dynamics. His work includes nonsimilar solutions of mixed convection flows of Newtonian and non-Newtonian fluids over various geometries, such as vertical cone, vertical slender cylinder and stretching surface, and flat surface. Dr. Patil has received Best Research Publication Award with citation from the Vision Group on Science and Technology, Government of Karnataka. He made a research paper entitled “Unsteady mixed convection flow from a moving vertical plate in a parallel free stream: Influence of heat generation or absorption” for the year 2010-2011 in Mathematical Sciences. Dr. Patil has been visiting many research institutions for collaborative research, such as IIT Chennai, TIFR-CAM, Bangalore, and IISc Bangalore.
