Numerical Computation of a Two-Dimensional Biomagnetic Channel Flow

Abstract

The present paper studies the fundamental problem of the biomagnetic fluid flow in a channel under the influence of a spatially varying magnetic field. The solution of the problem is obtained using an improved finite difference method. This approach has successful handled the pressure of the flow which is the main problem in the finite difference method. Results concerning the velocity indicates that the presence of magnetic field appreciably influence the flow field. A distortion in terms of asymmetric flow profile was observed near the magnetic source. Also a vortex is demonstrated near the lower plate where the magnetic source is placed.

The effect of magnetisation and Lorentz forces in a two-dimensional biomagnetic channel flow

“…It is therefore evident that our improved numerical algorithm also can handle a problem which is driven by pressure gradient. It is constructive to note that the flow previously studied in Rusli et al [18] is driven by velocity gradient. Our original reference which is based on a numerical algorithm proposed by Zogheib [15] can only handle for flow which is driven by velocity gradient.…”

“…The solution of the governing equations presented in the equations (7) to (9) subject to the boundary conditions in the equations (10) and (11) are solved numerically using the improved finite difference method as described in our previous work [18]. A first-order upwind differencing scheme is used to approximate the convective terms in the momentum equations, while a second-order central differencing is used for the diffusion terms.…”

“…Ramamurthy and Shanker [16] investigated the non-Newtonian blood flow using electromagnetic technique. A finite difference scheme with SIMPLE-type algorithm was used by Rusli et al [17] to analysis the biomagnetic fluid mechanism. The governing equations, which are basically nonlinear PDEs are solved by using staggered grid.…”

CYP505E3: A Novel Self‐Sufficient ω‐7 In‐Chain Hydroxylase

“…[24] Additionally, CYP505E3 could be employed for the synthesis of valuable diols and lactones. Alternative biocatalytic processes for the synthesis of C10 and C12 d-lactones are highly sought after [4,22] given that expensive natural substrates, variable supply, and environmental concerns [25] present challenges to processes currently used for the industrial production of "natural" lactones from unsaturated massoia d-lactones.
