Abstract:- Efficiency considerations in steam turbine moving blades involve predicting the dynamic behavior using mechanical structure vibration theory. The evaluation of blade designs relies on understanding dynamic behavior and fluctuating forces. The primary design focus is on minimizing dynamic stresses induced by fluctuating forces. As these forces exhibit periodicity, achieving resonance with blade natural frequencies becomes crucial, often assessed through a Campbell diagram. The study encompasses estimating dynamic behavior, analyzing centrifugal force stresses in the final stage, and evaluating disc groove stresses at root contact. The research involves comprehensive analyses, including mode shapes and natural frequencies determination, and validation through Campbell diagrams against experimental data. Due to the blade's unique length and twist, accurate geometry determination requires extensive input. The blade's geometry is established by various profile data at different heights. The findings and conclusions from this research contribute valuable insights into steam turbine blade durability.

Abstract:-In this study, the evaluations of the impact of the tube bundle configuration in a horizontal, two-pass condenser on the heat transfer to the flowing water are presented.    In a cross-flow configuration with a downward superheated steam flow, the tube bundle is believed to function as a staggered tube bank.    It is presumed that the recirculating saturated water is undergoing turbulent movement.  By applying the formulas for heat transfer via tube banks—which include factors like vapor shear, condensate inundation, and the impact of tube surface geometry—to six different tube layouts, we can find the one that causes the most significant change in the temperature of the flowing water.  A number of parameters, including the condenser and tube materials, the geometry of the tubes, the spacing between the tubes, the amount of condensate inundation, and the steam velocity, determine the system's heat flux.    To back up the analytical findings, numerical models of the six tube configurations were created using a Reynolds-averaged Navier-Stokes (RANS) method.  The ideal tube configuration for maximal heat transmission to the flowing water is attempted to be determined by analyzing the analytical and numerical results from the six configurations evaluated.  The results show that the steam-air combination velocity profile determines the circulating water temperature.  When the steam-air mixture velocities are greatest, the heat transmission is greatest in the rows of tubes.    A larger fluctuation in the temperature of the circulating water will result in a more pronounced velocity profile.
