Experimental determination of turbulent forced convection heat transfer and friction factor with SiO2 nanofluid

TL;DR: In this paper, the heat transfer coefficients and friction factor with SiO2/water nanofluid up to 4% particle volume concentration are determined for flow in a circular tube under constant heat flux boundary condition.
Journal ArticleDOI

Laminar convective heat transfer with twisted tape inserts in a tube

TL;DR: In this paper, a new method is postulated to predict heat transfer coefficients with twisted tape inserts in a tube, in which the wall shear and the temperature gradients are properly modified through friction coefficient correlation leading to heat transfer augmentation from the tube wall.
Journal ArticleDOI

Convective condensation of vapor in the presence of a non-condensable gas of high concentration in laminar flow in a vertical pipe

TL;DR: In this paper, the authors formulated the problem of laminar film condensation of vapor in the presence of high concentration non-condensable gas such as humid air flowing in a vertical pipe under Laminar forced convection conditions.
Journal ArticleDOI

A combined approach to predict friction coefficients and convective heat transfer characteristics in A tube with twisted tape inserts for a wide range of Re and Pr

TL;DR: In this paper, generalized correlations are evolved to predict friction factors and convective heat transfer coefficients with twisted tapes in a tube for a wide range of Reynolds numbers and Prandtl numbers.
Journal ArticleDOI

Heat transfer from a horizontal fin array by natural convection and radiation—A conjugate analysis

TL;DR: In this paper, the authors formulated the problem of natural convection heat transfer from a horizontal fin array by treating the adjacent internal fins as two-fin enclosures, and the numerical solutions by using alternating direction implicit (ADI) method yield steady state temperature and velocity fields in the fluid, and temperatures along the fins.
