It　is　well　known　that　the　flow　and　clarification　process　of　glass　melt　are　critical　to　glass　production　control　and　product　quality.　To　explore　the　flow　characteristics　and　clarification　process　of　glass　melt　in　float　glass　furnace,　the　flow　field　and　temperature　distribution　were　studied.　From　a　new　perspective　the　numerical　simulation　of　the　flow　and　heat　transfer　process　of　glass　melt　were　carried　out　for　a　glass　tank　under　actual　working　conditions　by　using　Ansys　CFD　software.　In　view　of　the　simulation　results　on　flow　field　and　heat　transfer　of　glass　melt　in　float　glass　furnace,　the　temperature　distribution　and　flow　characteristics　of　glass　melt　in　the　furnace　were　analyzed　and　the　clarification　process　of　the　bubbles　in　glass　melt　was　further　analyzed　on　this　basis.　It　was　found　that　along　the　furnace　length,　the　temperature　of　the　glass　melt　on　the　surface　and　at　the　bottom　of　the　tank　showed　two　mountain　shaped　distributions　respectively,　and　the　flow　pattern　of　glass　melt　presented　three　large　circulation　flows　in　the　tank.　In　the　clarification　section　the　forward　and　backward　flow　velocities　of　glass　melt　increased　and　then　decreased.　In　the　direction　of　tank　depth　from　surface　to　bottom,　the　temperature　of　glass　melt　decreased　in　a　gradient.　At　a　depth　of　about　400　mm　from　the　surface,　the　value　of　flow　velocity　was　zero.　After　the　hot　spot,　the　flow　above　this　surface　flowed　smoothly　to　the　neck,　and　at　the　shortest　time　of　418　s.　Within　this　time,　bubbles　larger　than　1.2　mm　in　diameter　can　be　eliminated　before　they　reached　the　neck　with　the　flow　of　glass　melt,　and　whether　the　bubbles　smaller　than　1.2　mm　in　diameter　can　be　eliminated　or　not　needs　further　study　on　the　pattern　of　bubble　uplifting　and　changing.　©　2024　Science　Press.　All　rights　reserved.
