Several studies have indicated that responses to policies intended to reduce car use may fall short of the predicted or desired response, suggesting a need for improved behavioral models. One basis for improvement is to better account for population heterogeneity. In particular, studies show that men and women have different transportation patterns based on gender-related characteristics, roles in families and access to facilities; these differences can be manifested in their mode choice in the presence of demand management strategies. Based on stated preference mode choice data, gathered from a sample of Tehran’s commuter drivers to the CBD (of 192 women and 385 men), this study uses three... 

Injection of jet into cross-flow has various applications, such as film cooling of gas turbine blades, reaction control jets for missiles and aircrafts, and mixing of air and fuel in combustion chambers. Velocity ratio (blowing ratio), momentum ratio, and streamwise jet inclination angle are important correlation parameters which have been studied extensively. However, not much work has been done on the jet swirling effects. The present work investigates computational simulation of a row of swirling square jets injected normally into a cross-flow. The swirl is introduced using two injectors discharged normally into the jet. Computational simulations were performed using LES approach with...
