Flow of Giesekus viscoelastic fluid in a concentric annulus with inner cylinder rotation

Viscoelastic fluid behavior in annulus using Giesekus model

“…As can be seen from Fig. 4 for˛≤ 0.3, even though the percentage of truncation error is small but we cannot go to high Deborah numbers because of stability limitations as pointed out above [4,6].…”

“…(11) or (12) and the approximation validity condition, i.e. * rz < 1/2 √ 2˛De should be satisfied simultaneously [6].…”

“…The Giesekus model is being employed increasingly to predict the flow and heat transfer of viscoelastic fluids: recent papers include those of Yoo and Choi [4], Schleiniger and Weinacht [5], and Rashidi et al [6,7] among others.…”

The effects of Soret and Dufour, chemical reaction, Hall and ion currents on magnetized micropolar flow through co-rotating cylinders

“…Subject to the following initial conditions: y 1 (1) = 1, y 3 (1) = 1, y 5 (1) = 1 and y 8 (1) + S r S c y 6 (1) = 0 (17)…”

“…3 Many other hypothetical studies have been reported in current years (Richard et al 4 ). Ravanchi et al 5 Examined the Giesekus flow through viscoelastic fluid in the annulus with inner cylinder rotation. The dissipative, radial, MHD on Newtonian flow through the horizontal annulus with rotating outer cylinder has been studied by Mozayyeni and Rahimi.…”
