A din\u00e2mica de fluidos<\/strong>\u00a0\u00e9 uma parte importante da maioria dos processos industriais;\u00a0especialmente aqueles que envolvem a
\ntransfer\u00eancia de calor.\u00a0Nos reatores nucleares,<\/strong>\u00a0<\/a>a remo\u00e7\u00e3o de calor do\u00a0n\u00facleo<\/a>\u00a0do\u00a0reator<\/a>\u00a0\u00e9 realizada passando um l\u00edquido refrigerante l\u00edquido ou gasoso atrav\u00e9s do n\u00facleo e por outras regi\u00f5es onde o calor \u00e9 gerado.\u00a0A natureza e a opera\u00e7\u00e3o do sistema de refrigera\u00e7\u00e3o s\u00e3o uma das considera\u00e7\u00f5es mais importantes no projeto de um reator nuclear.<\/p>\n

O fluxo de fluido<\/strong>\u00a0no campo nuclear pode ser complexo e nem sempre est\u00e1 sujeito a rigorosas an\u00e1lises matem\u00e1ticas.\u00a0Ao contr\u00e1rio dos s\u00f3lidos, as part\u00edculas de fluidos se movem atrav\u00e9s de tubula\u00e7\u00f5es e componentes em velocidades diferentes e s\u00e3o frequentemente sujeitas a diferentes acelera\u00e7\u00f5es.\u00a0Os axiomas fundamentais da din\u00e2mica de fluidos s\u00e3o as leis de conserva\u00e7\u00e3o, especificamente, conserva\u00e7\u00e3o de massa (levando \u00e0 equa\u00e7\u00e3o de continuidade), conserva\u00e7\u00e3o de momento linear e conserva\u00e7\u00e3o de energia.<\/p>\n<\/div>\n<\/div>\n
