Abstract：Inflowfieldsimulationsofcigartobaccodryingrooms，thetreatmentof intermaltobaccoisanimportantfactor affecting the acuracyof numericalsimulation.Toreduce thecomplexityof themodeland improve theeficiencyof the solution，using porous media models tosimplifythetobaccoisacommon method．Toexplore the influenceof different modeling methods on the simulationacuracy ofairflow resistane，this paper establishes threeporous media models based on theporous mediatheoryandconsiders theinfluenceoftobaccoleafmorphologicalchanges.Comparisonresultsshowthatthe anisotropic porous media models show an average relative error of 2. 45% ， -0.25% and 3.92% for pressure drop in the x ， （20 y and z directions respectively，significantly lower than thatof theisotropic porous media model.In the numerical simulation of the flow field，the average relative errors of the anisotropic porous media model at diferent locations are -3.12% ， （204号 4.67% and 2.95% ，respectively. The results show that the anisotropic porous media model can accurately describe the obstruction efectoftobacco leaves on theairflow，andcanobtainmoreaccurate simulationresults for theairflowresistance changes caused by the airflow from different directions through the tobacco leaves and leaf morphological variations.
