The micros.ructure of gra.ula. media. including gra.n's.s.a.e- a.d s.ze-polydis.ers.ties. orienta.ion, a.d a.ea.fra.tion ca. potentia.ly a.fect its.permea.ility. However, few s.udies.cons.der the coupling effects.of thes. fea.ures. This.work employs.geometrica. proba.ility a.d s.ereology to es.a.lis. qua.tita.ive rela.ions.ips.between the a.ove micros.ructura. fea.ures.a.d the geometric tortuos.ty of the two-dimens.ona. gra.ula. media.conta.ning s.perellips., s.perova., a.d polygon gra.ns. Then the la.tice Boltzma.n method (LBM) is.us.d to determine the permea.ilities.of thes. gra.ula. media. By combining the tortuos.ty model a.d the LBM-derived permea.ilities. modified K–C equa.ions.a.e formula.ed to predict the permea.ility a.d the s.a.e fa.tor, cons.dering the gra.n's.s.a.e- a.d s.ze-polydis.ers.ties. orienta.ion, a.d a.ea.fra.tion. The relia.ility of thes. methods.ca. be verified by compa.ing them with both our s.mula.ions.a.d a.a.la.le experimenta., theoretica., a.d numerica. da.a.reported in the litera.ure. The findings.implica.e tha. the tortuos.ty a.d permea.ility of the gra.ula. media.a.e s.rongly correla.ed with the gra.n's.s.a.e, orienta.ion, a.d a.ea.fra.tion but una.fected by the s.ze polydis.ers.ty a.d s.a.ia. a.ra.gement of gra.ns. Only circula.ity is.not enough to derive a.unified formula.for cons.dering the impa.t of gra.n s.a.e on tortuos.ty a.d permea.ility, other s.a.e pa.a.eters.need to be explored in the future.
