The critical Ohnesorge number that ensures transition from the inertial to viscous regime was 0.03, and the time- scale factor value that defines the transition from collapse-penetration mode (CPM) to impact-penetration mode (IPM) was found to be 0.04. Full size image Figure 2c shows the ...
A drop-size distribution is uniform for drops with diameters between 0 and 5 mm, and equals 10 m−3 mm−1. (a) Which drops contribute most to the reflectivity factor? (b) Determine the reflectivity factor in dBZ units. (c) Assume that the terminal velocity of drops is given by Eq...
As a safety factor, a large unloading pressure gradient is used, independently of the type of fluids that are currently in the well, so that in the future the well can be unloaded with any type of completion fluids. If the unloading-liquid pressure gradient is not known, it can be ...
The results show that a rise in the Weissenberg number, the viscosity ratio, the Weber number, and the mobility factor of the viscoelastic fluid leads to an increase in both the dimensionless height and radius of the crown, while increasing the Bond number leads to a decrease in the growth ...

Maxwell [1] derived a “static” thermal conductivity model for conventional fluids containing at that time micrometer/millimeter particles. It was assumed that the effective thermal conductivity of the mixture is a function of the thermal conductivity of the suspensions and the base fluid as well ...

pressure drops across the thin layers of electrospun nanofiber filters are not proportional to the thickness. This might be a critical factor for obtaining precise pressure drops across the electrospun nanofiber filters with extremely thin layers. Finally, we derived the product of drag coefficient and...
First, a comprehensive range of parameters has been investigated, with drop sizes spanning a factor of 105 in drop volume (30 pl to 4 μl) and substrate liquid absorption rates between 6 ml m−2s−1 and 710 ml m−2s−1. Second, the focus is set on a qualitative ...
