  • Constructal flow orientation in conjugate cooling channels with internal heat generation 
    Bello-Ochende, Tunde; Olakoyejo, O.T. (Olabode Thomas); Meyer, Josua P.; Bejan, A.; Lorente, S. (Elsevier, 2013-01)
    This paper presents the development of the three-dimensional flow architecture of conjugate cooling channels in forced convection with internal heat generation within the solid for an array of circular cooling channels ...
  • Constructal multi-scale pin fins 
    Bello-Ochende, Tunde; Meyer, Josua P.; Bejan, A. (Elsevier, 2010-06)
    In this paper we use constructal theory to determine the configuration of two rows of pin–fins so that the total heat transfer rate is maximized. The heat transfer across the fins is by laminar forced convection bathed ...
  • The constructal size of a heat exchanger 
    Bejan, A.; Lorente, S.; Martins, L.; Meyer, Josua P. (American Institute of Physics, 2017-08-09)
    The architecture of heat exchangers is a classical subject that has been studied extensively in the past. In this paper, we address the fundamental question of what the size of the heat exchanger should be, in addition to ...
  • The constructal-law physics of why swimmers must spread their fingers and toes 
    Lorente, S.; Cetkin, E.; Bello-Ochende, Tunde; Meyer, Josua P.; Bejan, A. (Elsevier, 2012-09)
    Here we show theoretically that swimming animals and athletes gain an advantage in force and speed by spreading their fingers and toes optimally. The spacing between fingers must betwice the thickness of the boundary ...
