“…Flow problem in a porous tube or channel received much attention in recent years due to its various applications in medical engineering, for example, in the dialysis of blood in artificial kidney [1], in the flow of blood in the capillaries [2], in the flow in blood oxygenators [3], as well as in many http://ppr.buaa.edu.cn/ www.sciencedirect.com other engineering areas such as the design of filters [4], in transpiration cooling boundary layer control [5] and gaseous diffusion [6]. In 1953, Berman [7] described an exact solution of the Navier-Stokes equation for steady twodimensional laminar flow of a viscous, incompressible fluid in a channel with parallel, rigid, porous walls driven by uniform, steady suction or injection at the walls.…”

In this paper, laminar fluid flow and heat transfer in channel with permeable walls in the presence of a transverse magnetic field is investigated. Least square method (LSM) for computing approximate solutions of nonlinear differential equations governing the problem. We have tried to show reliability and performance of the present method compared with the numerical method (Runge-Kutta fourth-rate) to solve this problem. The influence of the four dimensionless numbers: the Hartmann number, Reynolds number, Prandtl number and Eckert number on non-dimensional velocity and temperature profiles are considered. The results show analytical present method is very close to numerically method. In general, increasing the Reynolds and Hartman number is reduces the nanofluid flow velocity in the channel and the maximum amount of temperature increase and increasing the Prandtl and Eckert number will increase the maximum amount of theta.

“…The parameters of the generalized Bessel polynomial were optimized using the particle swarm optimization algorithm. The results of the experiment showed the efficiency of the algorithm to define a parameter with lower error than previous work [7][8][9][10][11]. Moreover, this approach can apply for the simulation of matched filters to the 4 th side lobes with stability.…”

“…Bessel polynomials can write in form of generalized Bessel polynomials [6] that is used for applying in this paper. In the literature review of this paper, S. Mneina, et al [7] presented the linear phase matched filter using Bessel polynomials. However, this work is still far from an ideal response and illustrates only main lobe and one sidelobe.…”

This paper presents the study of mathematical characteristics of generalized Bessel polynomial that can be applied to approximate a sine-squared pulse for designing matched filters in communication systems. The proposed pulse can be designed by using the transfer function, in which the numerator is the five pairs of a transmissions zero pairs, and the generalized Bessel polynomial is used as the denominator. A parameters of generalized Bessel polynomials can be adjusted by particle swarm optimization to find the best parameter value. From the simulation results can be found that a parameter can be adjusted. A proposed pulse is close to the ideal response in mainlobe, and one sidelobe to four sidelobes with stability, which outperformed previous research.

“…The occurrence of laminar flow in ducts (tube or channel) with permeable walls gained much attention during passed years due to its numerous applications in bioengineering, for example in the flow of blood in dialyzer (artificial kidney) [1], glomerular filtrate in proximal convoluted tubule [2], blood in membrane oxygenators [3]. Moreover, its applications are found in transpiration cooling boundary layer control [4] as well as in the design of filters [5].…”

An analytical investigation is made to determine the heat and mass transfer mechanism of non-isothermal highly viscous uid in a long narrow porous channel. The walls of the channel are maintained at the same temperature. The mathematical model is developed by using the continuity, momentum, energy and diffusion equations. Analytical solutions are establish to get the expressions of velocity eld, pressure distribution, mass ow rate, wall shear stress, temperature profile, mass concentration distribution as well as the heat transfer rate (Nusselt number) and mass transfer rate (Sherwood number) with involved physical parameters. Numerical results are graphically sketched to describe the role of different parameters involved in the governing equations. It is observed that longitudinal velocity component is higher at the entrance region as compared to middle position and exit region of the channel. Temperature field decreases at the centerline of the channel with increasing suction (reabsorption) parameter. Concentration decreases from surface to the center of the channel and with increasing suction parameter concentration increases. Heat transfer rate decreases while mass transfer rate increases along the channel. With increasing Brinkman number heat transfer increases and its strength at the entrance region is higher than exit region.
