The　primary　objective　of　the　present　paper　is　to　investigate　the　novel　aspect　of　nanofluid　flow　near　the　stagnation-point　past　a　permeable　cylinder　with　chemical　reaction.　The　prescribed　surface　heat　and　nanoparticle　fluxes　are　also　taken　into　account.　The　improved　homotopy　analysis　method　is　introduced　to　obtain　the　recursively　analytic　solutions　with　high　precision.　The　convergence　of　the　obtained　series　solution　is　discussed　explicitly.　Besides,　the　effects　of　physically　significant　parameters　on　skin　friction　coefficient,　local　Nusselt　number,　local　Sherwood　number,　as　well　as　profiles　of　velocity,　temperature,　and　nanoparticle　volume　fraction　are　examined　and　discussed　in　detail.　It　is　found　that　the　local　Sherwood　number　increases　when　a　chemical　reaction　occurs　in　the　nanofluid.　It　is　also　indicated　that　the　increase　of　the　reaction　rate　parameter　leads　to　a　higher　temperature　and　a　lower　nanoparticle　volume　fraction.　©　2016　Wiley　Periodicals,　Inc.
