The present study proposes novel micro-jet impingement heat sink with effusion holes for flow extraction. The design consists of impingement nozzles surrounded by multiple effusion holes to take away the spent fluid. A three-dimensional numerical model is used for steady, incompressible, laminar flow and conjugate heat transfer for the performance analysis of the proposed design. The computatio...

SUMMARY Details are given of the static calibration of a hemispherrcal-headed drfferentral pressure yawmeter, 0.6 to 1.2; rn the Mach number range from the xnstrument has a central pitot pressure hole and two pairs of holes m perpendroular planes for flow directron measurement. The results show that ths sensitivity to yaw (for angles up to 8') as determined from pressure differences between opp...

This is a continuation of our earlier work where we constructed a phenomenologically motivated effective action of the boundary gauge theory at finite temperature and finite gauge coupling on S3×S1. In this paper, we argue that this effective action qualitatively reproduces the gauge theory representing various bulk phases of R-charged black hole with GaussBonnet correction. We analyze the syst...

We report a vertically-aligned liquid crystal display (LCD) device with submillisecond response time, high transmittance, and low operation voltage. The top substrate has a common electrode, while the bottom substrate consists of hole-patterned fringing-field-switching (FFS) pixel electrodes. A negative dielectric anisotropy LC is employed. In the voltage-on state, the LC directors are reorient...

Drilling a deep vertical well at low cost is very important for accelerating the exploration and development of oil gas resources. Vertical drilling BHA design key to drill well, however still an art not science in some formation. In this paper, new mechanical model bent-housing motor established, build rate prediction method considering formation properties presented uncertainties proposed. Th...

The in this issue. first depends on excitation–contraction coupling and is proportional to cardiac contractility. For the quiescent muscle the PVA and the oxygen cost of activation both are zero. The remaining part results from all other processes 1. Work output and efficiency of the heart...

Extraordinary 3D seismic data from the Central Offshore Platform (Southern North Sea), complemented by information 38 boreholes, reveal a 10 km-wide basement fault zone above which fluid anomalies emanate sub-salt reservoirs to terminate in lower Cretaceous strata. Fluid blow-out pipes, chimneys and low-amplitude trails were mostly sourced region where NW-striking syn-rift faults intersect N-st...

Micro-filters are fabricated using MEMS technology, and both measurements and numerical calculations are carried out in order to estimate the power requirement in a micron-size particle collection process using the microfilter. In order to numerically predict the pressure drop through the micro-filter, we focus on the characterization of the geometrical factors, such as internal profile of the ...
