A solar desalination plant for conditions in Turkey
(1989)In this study, it is supposed that a solar desalination plant has been installed in Antalya (36.5°N, 30.1°E), Turkey. The solar radiation incident on the ground has been determined and then an energy equilibrium has been ... -
An investigation of heat transfer gain with introduction of graphite powder to helium gas
(1993)Analysis is made of heat transfer by turbulently flowing helium gas with suspended graphite particles in a circular pipe. At very high temperatures, the radiative heat to gas alone can be profoundly improved because of the ... -
Numerical computation of turbulent flow in pipes
(1993)Developing turbulent flow in pipes of circular cross-section with length-to-diameter ratio of 100 has been computed at eight Reynolds numbers ranging from 3.8 X10 "SUP 4" to 3.88 X10 "SUP 5" . Numerical solutions of the ... -
Electronic and mechanical properties of stiff rhenium carbide monolayers: A first-principles investigation
(Elsevier Science BV, 2018)In this study, we predicted two new stable metallic Re-C based monolayer structures with a rectangular (r-ReC2) and a hexagonal (h-Re2C) crystal symmetry using first-principle calculations based on density functional theory. ... -
In pursuit of barrierless transition metal dichalcogenides lateral heterojunctions
(IOP Publishing LTD, 2018)There is an increasing need to understand interfaces between two-dimensional materials to realize an energy efficient boundary with low contact resistance and small heat dissipation. In this respect, we investigated the ... -
