Revolutionary turbine blade tip designs are critical for minimizing tip leakage losses in gas turbines. Several innovative designs, such as flat tips, squealer tips, tips with winglets and honeycomb cavities, have shown the potential to mitigate this problem.
Honeycomb tips offer a solution for mitigating turbine tip leakage flows. The tips are highly effective outperforming conventional flat tips.
Squealer tips provide a solution to various challenges in the tip gap region, such as reducing tip leakage flow and protecting blade tips from high-temperature gases. Further, they also improve design clearance through their sealing properties.
Hypersonic flow phenomena like shock waves, shock-boundary layer interactions and laminar to turbulent transitions require flow-aligned, high-resolution meshes. Hexahedral meshes judiciously discretize these flow physics regions, thereby aiding in accurately predicting their influence on the flow.
Alignment of grid lines with the flow aid in lower diffusion and numerical error, faster convergence and accurate capture of flow features. Read to know the subtle aspect of flow aligned grids and solution accuracy.
Complex ice shapes make generating well-resolved mesh extremely difficult, compelling the CFD users to make geometric or meshing compromises.
Scroll compressors with deforming fluid space, narrow clearances pose immense meshing challenges. Read to know about scroll meshing issues.
Developing a three-dimensional mesh for a scroll compressor with the challenges of the complicated moving geometries of the orbiting scroll and the deforming valves not only requires an automated meshing strategy but also a high quality structured mesh that produces higher accuracy of CFD results in a shorter turnaround time.
