Supersonic separators have found extensive applications in dehumidification of natural gases since 2003. Unlike previous studies, which have investigated the inlet conditions and nozzle geometry of supersonic separators for pure fluids, the present study employed a combination of momentum, heat, and mass transfer equations along with Virial equation of state (EOS) to inspect the effect of inlet...

In this study the wetting behavior of converging-diverging and diverging-converging capillaries is investigated numerically using an in-house written, finite-element code. An interface tracking procedure based on the predicted change in the total liquid volume, to update the interface location, and Cox's formulation, to determine the dynamic contact angle and the interface shape, is proposed an...

We present a comprehensive analytical and numerical study of shear-dominated flows Oldroyd-B fluids. Starting from transient ideal Couette flow, we show that less work is required to increase the shear rate than decrease it. Generalizing this observation non-homogeneous steady flows, reduced flow resistance around streamlines with increasing increased decreasing rate. demonstrate effect in smoo...

Commercially available cardiac scanners use 64–128 elements phased-array (PA) probes and classical delay-and-sum beamforming to reconstruct a sector B-mode image. For portable hand-held scanners, which are the fastest growing market, channel count reduction can greatly decrease total power cost of devices. The introduction ultra-fast imaging methods based on plane waves diverging provides new i...

We study two distinct effects of local religions on organizational risk-taking: religious beliefs share a common aversion to pure risk but have diverging attitudes toward speculative risk. As predicted, we find that mutual fund managers’ speculative risk-taking behaviors vary with specific local religious beliefs – funds in low-Protestant (or high-Catholic) areas have higher return volatilities...

[1] Alluvial fan deltas are built by aggrading and avulsing river channels. A numerical model of flow and sediment transport in channels is combined with a condition for channel avulsion to describe evolution of the fan surface. The model combines elements of two recent approaches: (1) diffusional models of depositional basin filling, which describe the evolution of overall morphology, and (2) ...

The motion of a suspension of red blood cells (RBCs) flowing in a Y-shaped bifurcating microfluidic channel is investigated using a validated low-dimensional RBC model based on dissipative particle dynamics. Specifically, the RBC is represented as a closed torus-like ring of ten colloidal particles, which leads to efficient simulations of blood flow in microcirculation over a wide range of hema...

This study presents an extensive numerical investigation on the flow characteristics of wormlike micellar (WLM) solutions past a single and vertically aligned two microcylinders placed in microchannel creeping regime. The rheological behavior solution is realized based two-species Vasquez–Cook–McKinley (VCM) constitutive model, which takes into account both breakage re-formation dynamics micell...
