ジャーナル フリーThe drought of 1994 in northern Shikoku was very severe, but Shikoku island as a whole has large amount of rainfall which causes flooding in the southern part. Regional unbalance of water resources is the main cause of the water problems in Shikoku island: flooding in the South and drought in the North. The circumstances of water in Sikoku island which cause the above mentioned problems are described from the view points of geography, regional rainfall distribution, discharge and water resources development of main rivers. The reasons for the recent tendency of increasing water shortage in Matsuyama are insufficient water resources development of groundwater or surface water, increase of water demand due to the growth of population and the change of life style to use more water. Besides these reasons, extremely small amount of rainfall in summer made the shortage of water disastrous in Matsuyama in 1994.抄録全体を表示PDF形式でダウンロード (8878K) -

ジャーナル フリーUsually, flow patterns of solid-liquid two-phase flow are discriminated by means of observing particle-bed situations, namely judging whether stationary or sliding bed. The usual method depends on observer's subjectivity. This work presents a new and objective method based on fluctuating intensity of particle velocity vectors measured by a particle tracking velocimetry (PTV). The relationship between the fluctuating intensity of deflection angles of the vectors and the modified Froude number is a good index to discriminate the flow patterns objectively. The flow patterns have been defined by crisp sets, however the definitions contain several contradictions. Analyzing uncertainty and ambiguity which are involved in the flow patterns and the process of judgment, the new definitions by means of considering fuzzy sets are proposed.抄録全体を表示PDF形式でダウンロード (1088K) -

ジャーナル フリーBubble behaviors in solid-liquid and liquid-liquid mixtures are analyzed by combining a viewpoint of multiphase flow with a conventional theoretical method of a single spherical bubble in liquid. A detailed model with a first order Mach number has been introduced and calculated numerically for the solid-liquid and liquid-liquid mixtures, respectively. The validity of the model is ascertained by comparing the bubble collapsing pressure with the previously reported measured data of cavitation erosion in liquid-liquid mixtures and a solid-liquid mixture. The numerical result shows that the bubble c6ollapse pressure decreases with increasing a solid phase.抄録全体を表示PDF形式でダウンロード (719K) -

ジャーナル フリーDistrict air-conditioning system using ice-water slurry for heat transfer have received considerable attention recently. Ice-water slurry offers potential cost savings since the distribution system can be constructed using smaller diameter pipes. An important design factor is pressure loss for ice-water slurry flows. Therefore, the purpose of this study is to investigate pressure losses for ice-water slurry flows for different pipe diameters. Pressure losses found experimentally by authors and others are investigated and a simple mathematical model to estimate pressure loss is proposed.抄録全体を表示PDF形式でダウンロード (901K) -

ジャーナル フリーAt present an advanced air conditioning facility having the higher efficiency in heat transportation and also reducing the cost of operation is required. However, the realization of such a facility depends on the appropriate use of multiphase flow because of the necessity of system composition. In the air conditioning field, a latent heat transportation technology has been developed by using ice as one of the working fluids. Here the current research on ice-water transportation for applying it to air conditioning is shown as a typical example of high technology using multiphase flow.抄録全体を表示PDF形式でダウンロード (3848K)
