["< sod > the'''stefan flow'' ', occasionally called'''stefan's flow'' ', is called a [ [ transport phenomenon ] ] usually concerning the movement of a [ [ chemical species ] ] by a flowing [ [ fluid ] ] ( typically in the [ [ gas phase ] ] ) that is induced to [ [ fluid dynamics | flow ] ] or by the production or removal of the species at such an [ [ interface ( chemistry ) | interface ] ]. any process that adds the species of interest to or removes... it from the flowing fluid may cause the stefan flow, but the other most common processes include [ [ evaporation ] ], [ [ condensation ] ], [ [ chemical reaction ] ], [ [ sublimation ( chemistry ) | sublimation ] ], [ [ ablation ] ], [ [ adsorption ] ], [ [ absorption ( chemistry ) | sodium absorption ] ], and [ [ desorption ] ]. it was named after the [ [ slovenes | slovene ] ] physicist, slovenian mathematician, and poet [ [ joseph stefan ] ] for his early work on calculating evaporation rates. < eod > < sod > the'''stefan flow'' ', occasionally called'''stefan's flow'' ', is a [ [ transport phenomenon ] ] concerning the movement of a [ [ chemical species ] ] by a flowing [ [ fluid ] ] ( typically in the [ [ gas phase ] ] ) that is induced to [ [ fluid dynamics | flow ] ] by the production or removal of the species there at an [ [ interface ( chemistry ) | interface ] ]. any process that adds the species of interest to or removes it from the flowing fluid may cause the stefan flow, but the most common processes include [ [ evaporation ] ], [ [ condensation ] ], [ [ chemical reaction ] ], [ [ sublimation ( chemistry ) | sublimation ] ], [ [ ablation ] ], [ [ adsorption ] ], [ [ absorption ( chemistry ) | absorption ] ], and [ [ desorption ] ]. it was named after the austrian physicist, mathematician, and poet [ [ joseph stefan | josef stefan ] ] for his early early work on calculating evaporation rates. < eod >"]
