The　treatment　of　sphere　contact　is　a　crucial　issue　on　the　numerical　analysis　of　the　flow　and　heat　transfer　in　packed　beds　of　particles.　In　this　work,　the　effects　of　three　different　methods　including　introducing　a　gap,　area　contacting　and　cylindrically　bridging　on　the　flow　and　heat　transfer　performances　of　structured　packed　beds　of　particles　are　investigated　with　CFD　methods.　The　simulation　results　have　shown　that　the　influence　of　different　treatment　methods　on　the　contact　point　on　flow　and　heat　transfer　gets　greater　as　the　porosity　decreases　and　the　Reynolds　number　increases.　There　are　no　large　differences　among　these　three　methods　on　the　pressure　drop　and　heat　transfer　under　laminar　flow　regime.　Compared　with　the　experimental　results,　cylindrically　bridging　method　is　proved　to　be　reasonable　to　simplify　the　sphere　sphere　contact　points.　Therefore,　cylindrically　bridging　treatment　method　is　encouraged　to　be　used　instead　of　point　contact　method　between　particles　with　CFD　analysis　in　structured　packed　beds　of　particles.
