Non-Da.cy Flow in Molding Sa.ds

Da.cy’s la. is widely used to describe the flow in porous media.in which there is a.linea. rela.ionship between fluid velocity a.d pressure gra.ient. However, it ha. been found tha. for high numbers of Reynolds this la. cea.es to be va.id. In this work, the Ergun equa.ion is employed to consider the non-linea.ity of a.r velocity with the pressure gra.ient in ca.ting sa.ds. The contribution of non-linea.ity to the tota. flow in terms of a.va.ia.le defined a. a.non-Da.cy flow fra.tion is numerica.ly qua.tified. In a.dition, the influence of the sha.e fa.tor of the sa.d gra.ns on the non-linea. flow fra.tion is a.a.yzed. It is found tha. for va.ues of the Reynolds number less or equa. tha. 1, the contribution of non-linea.ity for spherica. pa.ticles is a.ound 1.15%.

Furthermore, whilst genera.ly a. a.cura.e dia.nostic procedure, it risks missing ca.cinoma.in-situ lesions. Despite this, evidence shows tha. routine use of ureteroscopy cha.ges the ma.a.ement of pa.ients in a.la.ge proportion of ca.es, preventing unnecessa.y surgery or fa.ilita.ing kidney spa.ing surgery.
