Abstract The stability of flow in a lid‐driven cavity is investigated using an accurate numerical technique based on hybrid scheme with spectral collocation and high‐order finite differences. A global analysis carried out critical parameters are identified for various aspect ratios. It found that while there reasonable agreement the literature leading to loss square cavity, significant discrepancies cavities ratios 1.5 2. Simulations linearized unsteady equations confirm results from = 1,...
The effect of blockage on the onset instability in two-dimensional uniform flow past a cascade cylinders is investigated. same techniques as those described Gajjar & Azzam ( J. Fluid Mech. , vol. 520, 2004, p. 51) are used to tackle generalized eigenvalue problem arising from global stability analysis linearized disturbance equations. Results have been obtained for various mode classes, and our results show that odd–even modes, which correspond anti-phase oscillatory motion about...
Abstract The global stability analysis of the two–dimensional incompressible unsteady flow past a circular clinder cascade is studied using linear analysis. A new numerical technique used to find value critical Reynolds number that causes undergo Hopf bifurcation. An attempt has also been made study blockage effect on and associated Strouhal number.

Towards meeting the objective of simulating heat transfer processes in urban areas, study dispersion from a passive scalar area source has been addressed as first step, surface is some ways analogous to transfer. Some point measurement experiments have carried out by Pascheke et al. [15] mass urban-like geometries using naphthalene sublimation technique. Large eddy simulations these are performed validation and details, presented here, demonstrate influence largest buildings on processes.
Risk assessment, city planning, and emergency response are a few examples of potential applications scalar dispersion in urban environments. The complex flow fields passive determined by the building layout prevailing meteorological conditions that highly uncertain nature. These quantities from field measurements provided as inputs to Reynolds-averaged Navier-Stokes (RANS) simulations investigate their effects predicting central London. After validating mean wind with large eddy wind-tunnel...
