geometry of the chute blocks in stilling basins plays a significant role in size and type of these structures. one of the most influencing factors in the design of the blocks is the fluctuating pressure which may cause fatigue on the blocks. despite investigations conducted by many researchers, there is not enough information about the pressure fluctuation around chute blocks in compacted still...

in this study, the turbulent kinetic energy redistribution process is investigated. to this aim, the direct numerical simulation (dns) of incompressible flow of a newtonian fluid through a channel at a shear reynolds number of reτ = 180 is used to produce a flow data base. then, these data are statistically analyzed. the turbulent kinetic energy redistribution is studied using the pressure-stra...

the main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the qeshm channel. for this purpose, the curves of the pressure on the persian gulf and oman sea, during the passing of the atmospheric low pressure system, are extracted across the region. during the time of occurrence of these events, sea level oscillations in the coastal areas of...

The energy equation for turbulent flow of fiber suspensions was derived in terms of second order correlation tensors. Fiber motion of turbulent energy including the correlation between pressure fluctuations and velocity fluctuations was discussed at two points of flow field, at which the correlation tensors were the functions of space coordinates, distance between two points, and time.

introduction: this study aimed to investigate the diurnal intraocular pressure fluctuations under dehydration conditions and the relationship between the intraocular pressure fluctuations and blood pressure. methods: the intraocular pressures (iop), body weights, as well as systolic and diastolic blood pressures (sbp, dbp) of 36 fasting healthy volunteers were recorded at 8:00 a.m. and 5:00 p.m...
