BACKGROUND In addition to conventional approaches, detecting and characterizing CTCs in patient blood allows for early diagnosis of cancer metastasis. METHODS We blended poly(ethylene oxide) (PEO) into nylon-6 through electrospinning to generate a fibrous matbased circulating tumour cells (CTCs) assay. The contents of nylon-6 and PEO in the electrospun blend fibrous mats (EBFMs) were optimize...
The effect of inclination angle on the steady laminar free convection in a rectangular enclosure (aspect ratio = 5), which is discretely heated by an isoflux flush mounted small heater (L / H = 0.125) is studied numerically. The local and average Nusselt numbers are compared at inclination angles from 0 (bottom heating) to 180o (top heating), for modified Rayleigh numbers 102 ≤ Ra* ≤ 106. The t...
singular perturbation problems have been studied by many mathematicians. since the approximate solutions of these problems are as the sum of internal solution (boundary layer area) and external ones, the formation or non-formation of boundary layers should be specified. this paper, investigates this issue for a singular perturbation problem including a first order differential equation with gen...
in this paper, we consider an inverse boundary value problem for two-dimensional heat equation in an annular domain. this problem consists of determining the temperature on the interior boundary curve from the cauchy data (boundary temperature and heat flux) on the exterior boundary curve. to this end, the boundary integral equation method is used. since the resulting system of linea...
Theoretical analysis of magnetohydrodynamic fully developed forced convective flow and heat transfer characteristics a non-Newtonian electrically conducting Casson fluid through porous channel filled with anisotropic material bounded by two impermeable horizontal walls subject to constant flux applied the outer is investigated. The extended Darcy-Brinkmann model govern inside accounts for prese...
We investigate numerically the transition to unsteadiness of natural convection in air filled differentially heated cavities and cooled with uniform flux at their vertical boundaries. This is done using both time integration nonlinear equations linearized around a steady solution computation leading eigenvalues Jacobian solutions. Results are given for values aspect ratio ranging from 0.2 8. In...
the isogeometric analysis is increasingly used in various engineering problems. it is based on non-uniform rational b-splines (nurbs) basis function applied for the solution field approximation and the geometry description. one of the major concerns with this method is finding an efficient approach to impose essential boundary conditions, especially for inhomogeneous boundaries. the main contri...
a lattice boltzmann method is applied to demonstrate the comparison results of simulating natural convection in an open end cavity using different hydrodynamic and thermal boundary conditions. the prandtl number in the present simulation is 0.71, rayleigh numbers are 104,105 and 106 and viscosities are selected 0.02 and 0.05. on-grid bounce-back method with first-order accuracy and non-slip met...
