Characteristics of viscous fingering patterns in polymer solutions were investigated by radially pushing air in a radial Hele-Shaw cell containing hydroxypropyl methyl cellulose (HPMC) solutions. Low and high molecular weight HPMC samples were used. An increase in molecular weight easily yielded cha
