  • Analysis of the axisymmetric far wake 
    Yane, Tshepho; Narayana Rao, Subas Chandar (Botswana International University of Science and Technology, 2017-06)
    The axisymmetric turbulent far wake of a long slender cylinder is being studied. Classical analytical solutions describing the wake width and the velocity defect are presented. The governing equations have been solved with ...
  • Influence of the thermal radiation on the bioconvection of gyrotactic microorganism contains nanofluid 
    Shaw, Sachin; Narayana Rao, Subas Chandar; Prakash, Jagdish (Botswana International University of Science and Technology (BIUST), 2017-06)
    Microorganisms play a vital role to understand the ecological system and so it is very important to understand the behavior of microorganism due to different parameters. In the present paper, we implement a mathematical ...
  • Investigation of flow inside sharp bend elbows using numerical fluid mechanics. 
    Gadiile, Monametsi; Narayana Rao, Subas Chandar (Botswana International University of Science and Technology, 2017-06)
    Bent pipes and ducts are used extensively in the industrial complexes mainly due to space constraints. However, bends in pipes and ducts cause pressure losses and generate flow separation inside in the pipes and ducts ...
  • Numerical fluid mechanics study of effect of rear slant length on the drag of an idealized road vehicle 
    Mogotsi, Pako Pollard; Phologolo, Thato; Narayana Rao, Subas Chandar (Botswana International University of Science and Technology (BIUST), 2019-06)
    In all kinds of shapes and form road vehicles use up energy in the form of fuel. It is interesting to note that on the highway more than half of the useful energy output of the engine is used to accelerate and heat the ...
  • Study of effects of tailgates on the drag of an idealised road vehicle using numerical fluid mechanics 
    Bogatsu, Kenneth L.; Phologolo, Thato; Narayana Rao, Subas Chandar (Botswana International University of Science and Technology (BIUST), 2019-06)
    In all kinds of shapes and form road vehicles use up energy in the form of fuel. It is interesting to note that on the highway more than half of the useful energy output of the engine is used to accelerate and heat the ...
