Numerical Investigation of Nanofluid Forced Convection in Channels with Discrete Heat Sources

open access: yesJournal of Applied Mathematics, 2012
Numerical simulation is performed to investigate the laminar force convection of Al2O3/water nanofluid in a flow channel with discrete heat sources. The heat sources are placed on the bottom wall of channel which produce much thermal energy that must be ...

Design Method for Contra-Rotating Propellers for High-Speed Crafts: Revising the Original Lerbs Theory in a Modern Perspective

open access: yesInternational Journal of Rotating Machinery, 2012
The main theoretical and numerical aspects of a design method for optimum contrar-rotating (CR) propellers for fast marine crafts are presented. We propose a reformulated version of a well-known design theory for contra-rotating propellers, by taking ...

The aerospace plane design challenge: Credible computational fluid dynamics results [PDF]

open access: yes
Computational fluid dynamics (CFD) is necessary in the design processes of all current aerospace plane programs. Single-stage-to-orbit (STTO) aerospace planes with air-breathing supersonic combustion are going to be largely designed by means of CFD.
