Aircraft Engineering and Aerospace Technology Emerald Publishing This application is based on Japanese Patent Application No. Originality/value вЂ“ This paper is valuable for researchers in the new and upвЂђtoвЂђdate concept of the airfoil comprising a cross flow fan (Fanwing airfoil). So, this paper can be helpful for other researches involved in this topic as well as aerospace industries. This airfoil is very new and researches in this area are very limited. Practical implications вЂ“ This paper provides a detailed study of the Fanwing airfoil. This simplification leads to higher discrepancies between experimental data and numerical solution.

Research limitations/implications вЂ“ Because of complicated geometry of the airfoil, 2D analysis of the flow over the airfoil has been carried out. These forces will increase by enhancing the fan rotational speed.

It was showed that the airfoil lift and thrust are highly depended on the fan rotational speed.

It was shown that increasing free stream velocity or decreasing fan rotational speed leads to a larger trailing vortex and vice versa. At lowвЂђfan rotational speed, the eccentric vortex formed below the shaft of the fan but at highвЂђrotational speed, eccentric vortex came up and moved toward the airfoil leading edge. Some key flow features observed previously by experiments has also been reproduced by simulation, notably motion of the eccentric and trailing vortices. Both errors are generally acceptable for an engineering application. Findings вЂ“ CFD predicted lift force was in good agreement with experimental data with the error of 8.26 percent, while the error of thrust prediction was 14.17 percent. Finite volume method with rectangular computational cells was used for whole the solution domain. SecondвЂђorder upwind discretization was considered for the convection terms. The pressureвЂђvelocity coupling was calculated by the SIMPLEC algorithm. ReвЂђnormalization group k вЂђПµ model was used for turbulence modeling. At the airfoil solid walls no slip condition (zero velocity) was applied. Design/methodology/approach вЂ“ Flow over the airfoil has been investigated by CFD. Also, the airfoil trailing vortex size variation by free stream and fan rotational speed has been surveyed. The eccentric vortex motion observed earlier by other researchers in cross flow fan has been studied by numerical method. This research was going to find aerodynamic coefficients and static pressure distribution over the airfoil surfaces. Purpose вЂ“ The purpose of this paper is to show how flow over the airfoil comprising a cross flow fan has been solved by developing a computational fluid dynamics (CFD) code.
