GridPro’s Post

Delving into the intricate dynamics of ship maneuverability, CFD emerges as a crucial ally. In a recent simulation utilizing GridPro grids, fascinating flow details were observed during a rudder angle test at a straight-ahead condition. At a deflection of -35 degrees, the rudder revealed distinct flow separation zones, offering profound insights into its aerodynamic behavior. Through color-coded representations of axial velocity on a horizontal cut plane, the intricate interplay between the propeller disk and the rudder's influence on the flow dynamics was unraveled. The visualization vividly showcases the propeller's axial body force distribution and the pressure distribution along the rudder. Shades of blue delineate regions of heightened axial velocity, while hues of red indicate areas of elevated pressure, offering a comprehensive view of the flow phenomena. Such virtual tests serve as invaluable resources for comprehending ship maneuverability, paving the way for optimized designs and enhanced operational efficiency in maritime environments. #CFD #marine #shipping #decarbonisation #FluidDynamics #innovation #tech #Engineering #Simulation #NavalEngineering #Marine #mechanicalEngineering

The lifespan of a centrifugal pump is significantly influenced by vibrations and noise. The paths through which fluid leaks between the impeller and the housing are crucial to the overall fluid dynamics and acoustic efficiency of a hydraulic pump. As the clearance of the wear ring increases, both the pressure pulsation against the sidewalls and the normal vibration speed on the volute's outer surface tend to decrease. Conversely, the volute's efficiency improves when the clearance is reduced. #CentrifugalPump #CFD #ComputationalFluidDynamics #Mesh #Meshing #TurboMachinery #FluidDynamics #Simulation

Micro-turbine engines are becoming increasingly important in #aviation, especially for unmanned aerial vehicles (UAVs) and auxiliary #power units (APUs) in aircraft. These engines offer high rotational speeds despite their small size, with the KJ 66 model standing out as a robust example. However, due to their complex geometry, traditional tools struggle to measure performance parameters effectively, making Computational Fluid Dynamics (CFD) a vital tool for optimizing design and performance during testing. #MeshingMonday #Turbine #compressor #engine #aerospace #cfd #cae

In today's video, we will learn how to optimize the topology in terms of the number of blocks by removing the sheets of corners from the block structure. This method of delicately balancing the number of blocks and density in each block, aids in quicker grid convergence. This is also useful in cases where there is an upper limit in the number of blocks the CFD solver can use, or also in cases where the solver has its own partitioning algorithm.
