annuli造句
1. The geometric models of eccentric annuli flow field were established in the computational fluid dynamics PHOENICS-VR. 2. In addition, the decrease of the annuli gap will yield heat transfer deterioration during flowing in narrow annular channels. 3. More accurate calculation of pressure loss in narrow annuli of slim holes and coiled tubing operations is required. 4. The flowing state in narrow annuli changes apparently quicker than that in circular tube. 5. Results could reflect the basic characteristics of eccentric annuli flow well. 6. An experimental investigation on transient of wall temperature in start-up process of pool boiling heat transfer, on vertical plain tube and narrow annuli under atmospheric pressure, was carried out. 7. Atmospheric corrosion is generally associated with surface storage conditions, or with upper wellbore annuli that may not be fluid-filled. 8. Results show that there is a secondary flow in the belieal flow of the power law fluids in Eccentric annuli. Finally, the secondary flow is discussed. 9. Objective To evaluation the biomechanical changes on the vertebral body, annuli fibrosis and faced joint of the adjacent segments on the condition of anterior cervical discectomy and plant fixation. 10. Experiments were carried out to investigate the single-phase forced convection heat transfer with water in three vertical narrow annuli which were heated from inside by primary water. 11. The theoretical analysis of flow properties of power-law fluids and Bingham fluids in the eccentric annuli of horizontal section of wells is made. 12. Based on the present model, the theoretical calculation was performed to predict the flow characteristics for the developed flow in narrow annuli with the gap sizes of 1. 13. The velocity profile should be confirmed when non - Newtonian fluid flowing in duct and annuli is researched. 14. This program can be used to calculate temperature distributions multiple solid walls, liquid filled annuli and gas filled annuli Radiation heat transfer through gas filled annuli is included. 15. An experimental study on forced convection heat transfer of single-phase water in vertical and horizontal narrow annuli was performed. 15.try its best to gather and create good sentences. 16. The bipolar coordinate system in which the two boundary circles of eccentric annuli become the coordinate surfaces is used. 17. The key factors affecting frictional pressure loss in narrow annuli are changing annular dimensions, rotation and vibration of drill strings. 18. An experimental installation was designed and set up for investigating the mixed convection heat transfer when water flows upward through a vertical annuli filled with porous medium. 19. According to the principle of fluid mechanics, the law of laminar helical flow of power-law fluid in eccentric annuli is studied intensively in this paper.
