JKSIAM-v21n4 pp203-214 A Posteriori Error Estimators for the Stabilized Low-Order Finite Element
Discretization of the Stokes Equations Based on Local Problems Kwang-Yeon Kim
http://www.ksiam.org/archive/files/jksiam-2017v21p203.pdf

In this paper we propose and analyze two a posteriori error estimators for the stabilized P_1/P_1 finite
element discretization of the Stokes equations. These error estimators are computed by solving local Poisson
or Stokes problems on elements of the underlying triangulation. We establish their asymptotic exactness with
respect to the velocity error under certain conditions on the triangulation and the regularity of the exact
solution.

JKSIAM-v21n4 pp215-224 An Error Estimation for Moment Closure Approximation of  Chemical Reaction Systems
Kyeong-Hun Kim, Chang Hyeong Lee http://www.ksiam.org/archive/files/jksiam-2017v21p215.pdf

The moment closure method is an approximation method to compute the moments for stochastic models of chemical
reaction systems. In this paper, we develop an analytic estimation of errors generated from the approximation
of an infinite system of differential equations into a finite system truncated by the moment closure method.
As an example, we apply the result to an essential bimolecular reaction system, the dimerization model.

JKSIAM-v21n4 pp225-244 A numerical study on MHD natural convective heat transfer in an AG-water nanofluid
filled enclosure with center heater N. Nithyadevi, T. Mahalakshmi
http://www.ksiam.org/archive/files/jksiam-2017v21p225.pdf
The natural convective nanofluid flow and heat transfer inside a square enclosure with a center heater in the
presence of magnetic field has been studied numerically. The vertical walls of the enclosure are cold and the
top wall is adiabatic while the bottom wall is considered with constant heat source. The governing
differential equations are solved by using a finite volume method based on SIMPLE algorithm. The parametric
study is performed to analyze the effect of different lengths of center heater, Hartmann numbers and Rayleigh
numbers. The heater effectiveness and temperature distribution are examined. The effect of all pertinent
parameters on streamlines, isotherms, velocity profiles and average Nusselt numbers are presented. It is
found that heat transfer increases with the increase of heater length, whereas it decreases with the increase
of magnetic field effect. Furthermore, it is found that the value of Nusselt number depends strongly upon the
Hartmann number for the increasing values of Rayleigh number.

parallel porous plate channel in presence of chemical reaction M. Venkateswarlu, R. Vasu Babu, S.K. Mohiddin
Shaw http://www.ksiam.org/archive/files/jksiam-2017v21p245.pdf
The present investigation deals, Dufour and heat source effects on radiative MHD slip flow of a viscous fluid
in a parallel porous plate channel in presence of chemical reaction. The non-linear coupled partial
differential equations are solved by using two term perturbation technique subject to physically appropriate
boundary conditions. The numerical values of the fluid velocity, temperature and concentration are displayed
graphically whereas those of shear stress, rate of heat transfer and rate of mass transfer at the plate are
presented in tabular form for various values of pertinent flow parameters. By increasing the slip parameter
at the cold wall the velocity increases whereas the effect is totally reversed in the case of shear stress at
the cold wall. It is observed that the effect of Dufour and heat source parameters decreases the velocity and
temperature profiles.
