3	The Design of Compound Critical Sections for open Channel Flow Measuresurement Smith, R. L. 05 1900 (has links) <p> Weirs of the conventional shape are amenable to analysis based on an assumption of one-dimensional flow and a number of computational routines have been developed for this type of transition problem. When critical flow occurs in a highly non-uniform section, a more sophisticated approach is necessary. </p> <p> In conjunction with laboratory tests on a typical compound control, a mathematical mode was formulated for the development of the stage-discharge relation. It is felt that this model will allow an accurate prediction for water quantity from fluctuating sources. </p> / Thesis / Master of Engineering (MEngr) Open Channel Flow Measuresurement one-dimensional flow computational routines
4	Determination Of Hydraulic Parameters Of Semi-infinite Aquifers Using Marquardt Algorithm Taskan, Cuneyt 01 January 2004 (has links) (PDF) In this study, transmissivity and storage coefficient of a semi-infinite, confined, homogeneous and isotropic aquifer, where the flow is one-dimensional and linear, are determined using Marquardt algorithm, considering two independent cases: constant drawdown in the adjacent stream / or constant discharge from the aquifer due to pumping at a constant rate. In the first case piezometric head and discharge measurements are utilized. Hydraulic diffusivity, which is the ratio of transmissivity to storage coefficient, is determined from piezometric head measurements / whereas their product is determined from discharge measurements. Then, the two parameters are calculated easily. In the second case piezometric head observations are utilized only and transmissivity and storage coefficient are determined simultaneously. Convergence to true values is very fast for both cases even for poor initial estimates. Three examples, two using synthetic data for both cases and one using actual field data for the second case, are presented. Conventional type-curve matching method is used for comparison of the results. It is observed that the results of Marquardt algorithm are in a reasonable agreement with those of type-curve matching method. TC Hydraulic Engineering 1-978

6	Development of a Nordic BWR plant model in APROS and design of a power controller using the control rods / Utveckling av en nordisk BWR-anläggningsmodell i APROS och design av ett effektregleringssystem med hjälp av styrstavarna Al-Ani, Jonathan January 2021 (has links) In this master thesis an input-model of a Nordic BWR power plant has been developed in APROS. The plant model contains key systems and major thermohydraulic components of the steam cycle, including I&C systems (i.e. power, pressure, level and flow controls). The plant model is primarily designed for balance of plant studies at discrete power levels. The input-model of the power plant focuses especially on the steam cycle which is crucial for analysing water and steam behaviour and its influence on the reactor power. At the current stage, the model primarily handles steady-state conditions of full-power operation, which has been the design point. It has also been shown that reduced-power operation can be simulated with a reasonable trendline of pressure and temperature progression over facility components. / Inom ramen för examensarbete har en indatafil (modell) av en nordisk kokvattenreaktor, BWR, utvecklats i simuleringsverktyget APROS. Anläggningsmodellen är främst utformad för att simulera diskreta effektnivåer och innehåller viktiga system och termohydrauliska komponenter som ingår i ångcykeln, inklusive instrumenterings- och kontrollutrustning (dvs. effekt-, tryck-, nivå- och flödesreglering). Fokus har lagts särskilt på att få till en bra representation av ångcykeln, vilket är avgörande för analys av vatten- och ångbeteendet och dess påverkan på reaktoreffekten. Modellen kan främst användas för simulering av jämviktstillstånd vid full effektdrift och till en viss grad även reducerad effektdrift.

We formulated the flow of hydraulic circuit and the motion of moving parts, which were numerically simulated and experimentally confirmed. We confirmed that this stabilizing system functioned effectively and stably through the investigation: operation characteristics and stability of the stabilizing system, braking characteristics of a piston-dashpot system and operation characteristics of two hydraulic operating devices. Based on the results, we could perform an engineering development for stabilizing operation time of the hydraulic operating device. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University 遮断器油圧操作装置常時高圧安定回路方式数値解析一次元流れ気泡油柱分離駆動特性動作安定性油圧振動ダッシュポット制動特性同期駆動順次駆動 Circuit breaker Hydraulic operating device Hydraulic operation stabilizing system Numerical analysis One-dimensional flow Air bubble Hydraulic column separation Operation characteristics Motion stability Hydraulic vibration Dashpot Braking characteristics Synchronous drive Sequential drive
