Abstract Instantaneous 2D phosphor thermometry was performed on the windows and combustion chamber posts of an optically accessible dual-swirl gas turbine model combustor operated with CH4 at atmospheric pressure. Two phosphors were used in order to measure different surface temperature ranges: YAP:Eu (temperature range 850?K – 1150?K) YAG:Eu 1100?K 1300?K). Phosphor coatings applied post three...

Semi-transparent photovoltaic (STPV) windows, one of the building façade elements, can generate electricity and provide a certain amount daylight for occupants. Nevertheless, expensive cost unsatisfying indoor performance in room are common problems with STPV windows. This study investigates thermal, daylight, energy, life-cycle windows by considering varied window-to-wall ratios, orientations,...

agricultural waste fibers have been found to be suitable as reinforcement in cement-based composites, but studies on oil palm fiber as reinforcement in gypsum-cement wall panels are scarce. a mixture of two equal weights of gypsum and cement, with water-binder ratios of 0.45 and 0.55 were prepared. in each mix a varying percentage of fiber contents of 2%, 3% and 4% by weight of the binders were...

The fluid flow and heat transfer in lid-driven enclosures filled with Cu-water nanofluid is numerically investigated. The moving vertical walls of the enclosure  are maintained in a constant temperature, while the horizontal walls are insulated. The hybrid scheme is used to discretize the convection terms and SIMPLER algorithm is adopted to couple the velocity field and pressure in the momentum...

Background: In order to improve the evaluation of possible rectal toxicity based on the rectal normal tissue complication probability (NTCP), we consider the fractional dependence of the NTCP on the wall thickness (tW) and rectal displacement (RM). Materials and Methods: The two-dimensional NTCP model (NTCP2D) was developed using radiotherapy plans of ten randomly selected patients with prostat...
