Stagnation-point flow and heat transfer over an exponentially stretching/shrinking cylinder

Abstract

The stagnation-point boundary-layer flow and heat transfer over an exponentially stretching/shrinking cylinder is studied. The governing partial differential equations in cylindrical form are first transformed into ordinary differential equations which are then solved numerically using a shooting method. Results for the skin friction coefficient, local Nusselt number, velocity and temperature profiles are presented and discussed in detail. The effects of the stretching/shrinking parameter ɛ and the curvature parameter γ on the fluid flow and heat transfer characteristics are also examined. It is found that the solutions for a shrinking cylinder are non-unique and that the surface shear stress and the heat transfer rate at the surface increase as the curvature parameter increases.

Consequence of convective conditions for flow of Oldroyd-B nanofluid by a stretching cylinder

“…Utilizing the following conversions [4,19,29] After applying above conversions, Eq. (8) is automatically satisfied and Eqs.…”

“…Moreover, he noted that intensifying values of slip velocity and thermal conductivity parameters decline the local Nusselt number. Markin et al [4] analyzed the flow and heat transfer analysis toward shrinking/stretching cylinder with stagnation point. Stretched flow of a Jeffrey liquid with the impact of MHD and chemical species was deliberated by Hayat et al [5].…”

Suction Effect on Stagnation Point Flow and Heat Transfer over an Exponentially Shrinking Sheet in a Porous Medium

“…While, Rosali et al, [11] considered a rotating flow over an exponentially shrinking sheet with a suction effect. Merkin et al, [12] explored the stagnation-point flow and heat transfer over an exponentially stretching/shrinking cylinder and reported that as the curvature parameter increases, the heat transfer rate also increases and the solution for a shrinking cylinder is found to be non-unique.…”

Stagnation Point Flow Over a Permeable Stretching/Shrinking Sheet with Chemical Reaction and Heat Source/Sink

“…Meanwhile, Miklavčič et al [Miklavčič and Wang (2006)] were among the early researchers that investigated the flow over a shrinking sheet with the velocity moves towards the slit. Following this, the issue is becoming a common trend among the researchers which further emphasize the need to extend the problem of flow and heat transfer over a stretching/shrinking sheet to other different physical situations [Gupta and Gupta (1977); Bachok, Ishak and Pop (2010); Othman, Yacob, ; Nasir, Ishak and Pop (2017); Merkin, Najib, Bachok et al (2017); Jahan, Sakidin, Nazar et al (2018); Kamal, Zaimi, Ishak et al (2018)].…”
