Effect of a columnar defect on the shape of slow-combustion fronts
M. Myllys, J. Maunuksela, J. Merikoski +4
We report experimental results for the behavior of slow-combustion fronts in the presence of a columnar defect with excess or reduced driving, and compare them with those of mean-f…
Measurements of the instantaneous velocity difference and local velocity with a fiber-optic coupler
S. H. Yao, V. K. Horváth, P. Tong +2
New optical arrangements with two single-mode input fibers and a fiber-optic coupler are devised to measure the instantaneous velocity difference and local velocity. The fibers and…
Temporal Scaling of Interfaces Propagating in Porous Media
Viktor K. Horváth, H. Eugene Stanley
To better understand the temporal behavior of a roughening meniscus driven by capillary forces during the imbibition of a viscous fluid in porous media, we measure the height-heigh…
Anomalous density dependence of static friction in sand
Viktor K. Horváth, Imre M. Jánosi, Péter J. Vella
We measured experimentally the static friction force on the surface of a glass rod immersed in dry sand. We observed that is extremely sensitive to the closeness of pac…
