Asymmetrical non-uniform heat flux distributions for laminar flow heat transfer with mixed convection in a horizontal circular tube

Okafor, Izuchukwu F.; Dirker, Jaco; Meyer, Josua P. (Taylor and Francis, 2019)

Non-symmetric heat flux distributions in terms of gravity in solar collector tubes influence buoyancy-driven secondary flow which has an impact on the associated heat transfer and pressure drop performance. In this study ...
Constructal conjugate cooling channels with internal heat generation

Olakoyejo, O.T. (Olabode Thomas); Bello-Ochende, Tunde; Meyer, Josua P. (Elsevier, 2012-07)

This paper presents a geometric optimisation of conjugate cooling channels in forced convection with internal heat generation. Two configurations were studied; circular channels and square channels. The configurations ...
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 optimisation of conjugate triangular cooling channels with internal heat generation

Meyer, Josua P.; Olakoyejo, O.T. (Olabode Thomas); Bello-Ochende, Tunde (Elsevier, 2012-10)

This paper presents the development of the three-dimensional flow architecture of conjugate cooling channels in forced convection with internal heat generation within a solid. Two types of cross-section channel geometries ...
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 ...
Evaluation of single-phase, discrete, mixture and combined model of discrete and mixture phases in predicting nanofluid heat transfer characteristics for laminar and turbulent flow regimes

Onyiriuka, E.J.; Obanor, A.I.; Mahdavi, Mostafa; Ewim, Daniel Raphael Ejike (Elsevier, 2018-11)

It is essential to investigate the appropriate model for simulating nanofluid flow for different flow regimes because, at present, most previous studies do not agree with each other. It was, therefore, the purpose of this ...
Heat transfer and pressure drop characteristics of alternating clockwise and counter clockwise twisted tape inserts in the transitional flow regime

Abolarin, S.M. (Sogo); Everts, Marilize; Meyer, Josua P. (Elsevier, 2019-04)

The purpose of this study was to experimentally investigate the heat transfer and pressure drop characteristics in a smooth circular tube with alternating clockwise and counter clockwise twisted tape (CCCTT) inserts. The ...
Heat transfer characteristics of assisting and opposing laminar flow through a vertical circular tube at low Reynolds numbers

Everts, Marilize; Bhattacharyya, Suvanjan; Bashir, Abubakar Idris; Meyer, Josua P. (Elsevier, 2020-10)

Owing to its importance in industrial applications, many studies investigated mixed convective flow through vertical tubes. These studies usually considered tubes with relatively large diameters and short lengths. The ...
Laminar flow heat transfer enhancement in square and rectangular channels having : (1) A wire-coil, axial and spiral corrugation combined with helical screw-tape with and without oblique teeth and a (2) spiral corrugation combined with twisted tapes with oblique teeth

Emani, Madhu Sruthi; Ranjan, Hrishiraj; Bharti, Anand Kumar; Meyer, Josua P.; Saha, Sujoy Kumar (Elsevier, 2019-12)

Heat transfer enhancement is a vital area of research as it helps to design heat exchangers of reduced sizes and improved heat transfer rates. Thus, there is a pressing need for techniques which result in significantly ...
Laminar hydrodynamic and thermal entrance lengths for simultaneously hydrodynamically and thermally developing forced and mixed convective flows in horizontal tubes

Everts, Marilize; Meyer, Josua P. (Elsevier, 2020-10)

Correlations to predict the hydrodynamic and thermal entrance lengths in a smooth horizontal tube heated at a constant heat flux are often restricted to forced convection conditions. The reason being that most scholars do ...
Single-phase mixed convection of developing and fully developed flow in smooth horizontal circular tubes in the laminar and transitional flow regimes

Meyer, Josua P.; Everts, Marilize (Elsevier, 2018-02)

Correlations to calculate the local and average heat transfer coefficients for single-phase laminar flow in horizontal circular tubes with a constant heat flux boundary condition are usually restricted to fully developed ...
