PS natural circulation in single and multiple channel Adwani, PhD, 2007, 190 pages, energy systems engineering, IIT Bombay, Bovey Mumbai-400076. Director (s): Mr Kannan n Iyer summary this work is connected to a single-phase natural circulation (NC) in single and multiple channels. The main focus of this work include: fluid in NC cycle occurs from static movement, multi-channel multi-circular steady-state solutions, a stable border images. Attack movement in the NC circuit determines the delay in time change the mode of heat transfer is of great significance. Parameters influencing the onset time is determined through the equation of transient conditions. -Buckingham π theorem, influence the pathogenesis of dimensionless time number of dimensionless parameters was found to be 11 to determine the effect of each parameter extent independently using digital model of their choice. Omits the most effective and group the equality impact of parameter prediction of onset time and relevance to arrive. From literary works such as the correlation is expected to present experimental data and data in a quite good job. Multi-channel NC loop forecasts take into account the multiplicity of combinations of flow direction loop pressure drop is always zero. Algebraic design assumptions, such as the cooler temperature distribution prediction of indices of multiple liquidity ratio the same proportion of heat input. Multi-channel NC loop prediction experiments of flow combinations are considered to be achievable. This is NC loop through a two-channel as unidirectional and bidirectional case, NC loops and a three-channel confirmed. In these cases, through the analysis of the heat input rate is achieved at a given flow rate forecasts, regarded as a fair match the values observed and experiment. Single-phase NCCode developed for transient analysis of stability boundary was found almost the same image with a different node sizes. It shows the development code to catch transients at least numerical diffusion
