We investigate the dynamics of ferrofluidic wavy vortex flows in the counter-rotating Taylor-Couette system, with a focus on wavy flows with a mixture of the dominant azimuthal modes. Without external magnetic field flows are stable and pro-grade with respect to the rotation of the inner cylinder. More complex behaviors can arise when an axial or a transverse magnetic field is applied. Dependin...

The air-water two-phase flow plays an important role in many applications of industry fields. Usually, a 90-degree bend is used to connect pipes for changing the direction which influences pattern. In this paper, effect under different ranges gas and liquid superficial velocities on patterns horizontal pipe located after was experimentally investigated, then results were presented compared patt...

Peristaltic pumping induced by a sinusoidal traveling wave in the walls of a two-dimensional channel filled with a viscous incompressible fluid mixed with rigid spherical particles is investigated theoretically taking the slip effect on the wall into account. A perturbation solution is obtained which satisfies the momentum equations for the case in which amplitude ratio (wave amplitude/channel ...

Flow boiling in a straight\ rectangular channel was investigated to explore the conditions leading to critical heat ~ux "CHF#[ The ~ow channel had a 4[9×1[4 mm cross!section and 090[5 mm heated length^ heat was applied to the shorter dimension along only one wall[ Tests were performed with FC!61 liquid over a velocity range of 9[14 to 09 m s and at outlet subcoolings of 2\ 05 and 18>C[ Video im...

Experiments were performed to enable the development of a new theoretical model for the enhancement in CHF commonly observed with flow boiling on concave heaters as compared to straight heaters. High-speed video imaging and photomicrography were employed to capture the trigger mechanism for CHF for each type of heater. A wavy vapor layer was observed to engulf the heater surface in each case, p...

Aim and Objectives : The present study was aimed to nd gender differences in lip prints and rugae pattern and also to correlate particular lip print and rugae pattern. Methodology 150 individuals (75 male and 75 female) were included for the study. Lip prints were taken on the glued portion of cellophane strip and was stuck on the white bond paper. The grooves present on the middle portion of ...

Dimethyl ether is one of the derivative products coal that will be used as a household fuel substitute for LPG in Indonesia. In addition, it can also working fluid refrigeration system. To understand behavior this refrigerant, simulation was carried out to determine flow pattern dimethyl horizontal evaporator. This study applied an evaporator air conditioner with inside diameter 6.3 and 7.9 mm ...
