ジャーナル フリーThe rapid gas dynamic expansion in a free jet is used as a tool to investigate the creation of the condensed phase out of the gas phase by nucleation and cluster growth. Starting from experimental results that yield information about the existence of clusters and the heat transferred to the gas phase, the modeling of a gas-cluster system is presented using a molecular kinetic approach which considers the mass and energy transfer between gas and clusters in the free-molecular flow regime. Some numerical results are presented which show fair agreement with the experimental results. However, it is stressed that considerably more detailed information, which could possibly obtained now from numerical experiments, is needed to be able to further refine models for the fluxes at phase interfaces, especially for small systems.抄録全体を表示PDF形式でダウンロード (1354K) -

ジャーナル フリーThe flow patterns of the air-water two-phase flow in horizontal-upward inclined pipes were studied experimentally in order to obtain basic information on the flow characteristics of gas-liquid two-phase flows in hilly-terrain pipelines. Flow regime maps in horizontal-upward inclined pipes were expressed by the combination of a basic flow pattern and some auxiliary flow patterns. In addition to the effect of inclination angle on the flow pattern, their mutual relation between one in horizontal and others in inclined part was described. Comparisons of the flow regime maps with those obtained in single horizontal or upward inclined pipes without bending part were carried out.抄録全体を表示PDF形式でダウンロード (4094K) -

ジャーナル フリーAs a basis of designing unlined caverns for storage of liquid petroleum gas, terminal rising velocities VT and drag coefficient CD of single bubbles in a stagnant liquid filling in narrow parallel walls were measured in the present study using air and water at atmospheric pressure and room temperature. The gap width dδ of the parallel walls was varied from 300μm to 900μm. The bubble diameter de was from 1mm to 20mm. It was confirmed that VT was affected by δ as well as de. In addition, rising motion of a bubble was found to be classified into two states: one is the state of low VT when de is small and the other is that of high VT when de is large. Transition between these states was observed when de was intermediate size. Empirical correlations of VT and CD for each state were developed by taking into acount forces acting on a bubble.抄録全体を表示PDF形式でダウンロード (7816K) -

ジャーナル フリーThe effects of liquid viscosity on the rising velocity of a large gas bubble in a stagnant liquid, and on the flow parameters of slug flow were experimentally investigated using a 19.2mm diameter vertical tube with air and liquid as working fluids. The liquids used in the present experiment were water and glycerol solutions, and the kinematic viscosity of these liquids ranged from 0.83×10-6 to 15.5×10-6m2/s. The important parameters in slug flow such as the rising velocity of large gas bubbles, liquid slug length, liquid film thickness around large gas bubbles etc., were measured. As a result, it is clarified that the rising velocity of a large gas bubble in a stagnant liquid decreases only slightly with increasing liquid viscosity. On the other hand the rising velocity in flowing liquid, i.e., in slug flow increases with increasing liquid viscosity. These results are discussed in relation to the liquid film thickness around large gas bubbles. Furthermore, the mean values of gas and liquid slug lengths and the ratio of their standard deviations to mean values of their length are examined by paying attention on the effect of liquid viscosity.抄録全体を表示PDF形式でダウンロード (10417K) -

ジャーナル フリーThe correlation of droplet deposition rate is one of the most important constitutive equations in predicting the thermohydrodynamic behavior of annular dispersed flow based on the three fluid model. In view of this, quantitative comparison and evaluation of typical correlations of droplet deposition coefficient were made. The result indicated that the correlations show different dependencies on gas flux and droplet concentration and the considerable scattering in predicting the droplet deposition coefficient particularly for the higher gas fluxes and lower pressures.抄録全体を表示PDF形式でダウンロード (1625K) -

ジャーナル フリー流体の機能化、知能化を計る上で、混相流体の活用は重要な役割を演じるようになってきている。特に電磁場の作用下で高機能性を発揮する流体として磁性流体やER流体をベースとしてより高い付加価値を付けるための研究が活発化してきている。
本講座では、機能流体の代表例として磁性流体を取り上げ、その基礎から応用にわたる研究の道筋を4回シリーズで解説するものである。前回 [1] はその1回目として、混相流体的な側面から磁性流体をとらえて磁性微粒子を含む流体の特性について解説した。今回はそれに引き続いて、磁性流体の力学を扱う場合の基礎式を中心に磁性流体力学の成り立ちについて解説することにする。抄録全体を表示PDF形式でダウンロード (2036K) -
