Thermal Performance of a Receiver Tube for a High Concentration Ratio Parabolic Trough System and Potential for Improved Performance With Syltherm800-CuO Nanofluid
TL;DR: In this paper, the thermal performance of a high concentration ratio parabolic trough system and the potential for improved thermal performance using Syltherm800-CuO nanofluid were investigated and presented.
Journal ArticleDOI
Experimental measurement of viscosity and electrical conductivity of water-based γ-Al2O3/MWCNT hybrid nanofluids with various particle mass ratios
Solomon O. Giwa,Solomon O. Giwa,Mohsen Sharifpur,Mohsen Sharifpur,Josua P. Meyer,Somchai Wongwises,Somchai Wongwises,Omid Mahian,Omid Mahian +8 more
TL;DR: In this article, the effect of particle mass ratios of hybrid nanofluids on the thermal properties of deionized water (DIW)-based γ-Al2O3 and MWCNT hybrid nanoparticles was investigated.
Journal ArticleDOI
Falling film boiling and pool boiling on plain circular tubes: Influence of surface roughness, surface material and saturation temperature on heat transfer and dryout
TL;DR: In this paper, the influence of surface roughness and material on the heat transfer of falling film boiling and pool boiling on the outside of horizontal plain tubes has been investigated and the falling film enhancement factor and total dryout threshold were also measured.
Journal ArticleDOI
Topology optimization for the conduction cooling of a heat-generating volume with orthotropic material
TL;DR: The University of Pretoria and the South African National Research Foundation (NRF-DST) as discussed by the authors contributed to the work of this paper. But they did not specify the authorship.
Journal ArticleDOI
Empirical correlation between hub height and local wind shear exponent for different sizes of wind turbines
Shafiqur Rehman,Shafiqur Rehman,Luai M. Al-Hadhrami,Md. Mahbub Alam,Md. Mahbub Alam,Josua P. Meyer +5 more
TL;DR: In this article, the authors proposed a new correlation for the estimation of optimal hub height for harnessing the power of the wind on an economically competitive basis, and the optimal hub heights for Dhahran, Dhulom, Gassim, Juaymah and Rawdat Ben Habbas were found to be 64, 66, 81, 70 and 82 m, respectively.
