Didactic models in engineering education supported on virtual reality technology

  Techniques of virtual reality (VR) were applied on the development of models related to the construction activity within Civil Engineering education context. The interaction allowed by 3D geometric models could make an end to passive attitudes of learners as an opposition to traditional teaching systems. In addition, VR technology could be applied as a complement to three-dimensional (3D) modeling, leading to...

Entropy generation in convection over an inclined backward-facing step with bleeding

  The current work investigates entropy generation around an inclined backward-facing step under bleeding conditions using suction/blowing. The entropy generation is due to heat transfer and fluid flow in forced convection laminar flow in a duct with inclined step. The set of governing equations containing conservations of mass, momentum and energy are solved numerically to calculate the velocity and...
