Abstract

One method and two results are contributed to the complete understanding about MHD laminar flow in annular channel with transverse magnetic field in this paper. In terms of the method, a computationally cheap semi-analytic algorithm is developed based on spectral method and perturbation expansion. By virtue of the fast computation, dense cases with almost continuous varying Hartmann number $M$, Reynolds number $Re$ and cross-section ratio $\eta$ are calculated to explore the flow patterns that are missed in previous research. In terms of the results of inertialess regime, we establish the average velocity map and electric-flow coupling delimitation in $\eta$-$M$ space. Seven phenomenological flow patterns and their analytical approaches are identified. In terms of the results of inertial regime, we examine the law of decreasing order-of-magnitude of inertial perturbation on primary flow with increasing Hartmann number. The proposed semi-analytic solution coincides with the $Re^2/M^{4}$ suppression theory of Baylis & Hunt (J. Fluid Mech., vol. 43, 1971, pp. 423-428) in the case of $M<40$. When $M>40$, the pair of trapezoid vortices of secondary flow begins to crack and there is therefore a faster drop in inertial perturbation as $Re^2/M^{5}$, which is a new suppression theory. When $M>80$, the anomalous reverse vortices are fully developed near Shercliff layers resulting in the slower suppression mode of $Re^2/M^{2.5}$, which confirms the prediction of Tabeling & Chabrerie (J. Fluid Mech., vol. 103, 1981, pp. 225-239).

Abstract

In this study, the effect of heat shock on the cell membrane was investigated using molecular dynamics (MD) simulations. Specifically, we examined the structural and dynamic behavior of a 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) lipid bilayer as it was exposed to increasing temperatures ranging from 310K to 340K. The results revealed a significant transition in membrane behavior as temperature increased, particularly at 330K and 340K, where the bilayer exhibited characteristics of a fluid disordered phase. This transition was marked by an increase in the area per lipid, a decrease in bilayer thickness, and a reduction in the deuterium order parameter (Scd), indicating increased molecular disorder and membrane fluidity. Additionally, the number of hydrogen bonds between lipid head groups and surrounding water molecules declined, weakening electrostatic interactions and promoting bilayer permeability. At 330K and 340K, these changes contributed to the formation of transient pores, which could facilitate molecular transport across the bilayer. The optimal temperature for maintaining membrane stability while enhancing molecular diffusion was found to be 320K, where the bilayer retained an ordered structure and displayed increased lipid mobility without significant disruption. These findings provide valuable insights into the thermal regulation of membrane behavior, which has critical implications for processes such as drug delivery, gene transfection, and thermal therapy. Molecular dynamics simulations at the atomistic level allow us to uncover intricate details of membrane phase transitions that are challenging to observe experimentally. [ABSTRACT FROM AUTHOR]
