Casson-Williamson　(CW)　nanofluid　flows　and　mass　transfer　characteristics　are　explored　in　this　study.　Furthermore,　the　velocity　slip　condition　and　viscous　dissipation　affect　or　are　taken　to　examine　the　changes　in　mass　and　heat　transfer　caused　by　a　stretching　surface　integrated　into　permeable　media　with　heat　conversion　beneath　the　effect　of　a　magnetic　field　and　consistent　thermal　radiation.　All　the　physicochemical　characteristics　of　the　non-linear　fluids　are　regarded　massive.　Whether　or　not　the　concentration　of　nanofluids　remains　stable　is　investigated.　When　particles　of　a　nanofluid　are　in　motion,　chemical　reactions　can　occur,　and　this　motion　can　be　used　to　study　the　concentration　of　the　nanofluid.　One　must　first　examine　a　set　of　non-linear　partial　differential　equations　with　boundary　conditions　as　a　base　equation　to　obtain　the　necessary　BVP　mathematical　model.　The　approximate　solution　for　differential　equations　was　found　using　the　finite　difference　method,　which　also　considered　the　necessary　boundary　conditions.　The　numerical　analysis　results　are　then　represented　visually　to　demonstrate　how　different　governing　parameters　affect　velocity,　temperature,　and　concentration.　Although　the　heat　transmission　exhibits　a　reverse　manner,　the　non-Newtonian　nanofluid　moves　more　quickly　in　the　non-appearance　of　a　magnetic　domain　than　it　does　in　one.　Additionally,　as　the　porosity　parameter　increased,　the　heat　transmission　rate　decreased,　whereas　the　skin　friction　coefficient　increased.　The　novel　parts　of　this　study　come　from　the　simulation　findings　of　a　non-Newtonian　CW　nanofluid　model　in　porous　media　subjected　to　a　magnetic　field,　heat　radiation,　and　slip　velocity　phenomena.
