Abstract: Heat transfer enhancement in horizontal annuli using variable thermal conductivity and variable viscosity of CuO-water nanofluid is investigated numerically. The base case of simulation used thermal ...

Abstract: In this research, ndodecylthiol was added to P3HT/PC70BM polymer solar cells (PSCs) to improve the crystallinity of P3HT and enhance the phase separation of P3HT/PC70BM. Crystallinity of P3HT:PC70BM doped with 0–5% by ...

Abstract: The power law and log law velocity profiles and an integral analysis in a turbulent wall jet over a transitional rough surface have been proposed. Based on open mean momentum Reynolds equations, ...

Abstract: In transitional rough pipes, the present work deals with alternate four new scales, the inner wall transitional roughness variable ζ=Z+∕ϕ, associated with a particular roughness level, defined ...

Abstract: The novel scalings for streamwise variations of the flow in a turbulent wall jet over a fully smooth, transitional, and fully rough surfaces have been analyzed. The universal scaling for arbitrary wall roughness is considered ...

Abstract: In a recent paper, work of Jordan [1] has pointed out that “measurements of Lueptow et al. [2] did not confirm the empirical expression خ´/a=0.45(x/a)0.746 proposed by Afzal and Singh [3], but however supports the general ...

Abstract: The theory of a new damper is derived and verified experimentally. The damper utilizes an electric armature elastically coupled to its field stator which is fixed to the vibrating system. The ...

Abstract: A method is presented that leads to accurate estimation of the cumulative fatigue damage incurred in a randomly loaded structural element when loading is given in the form of spectral density ...

Abstract: Numerous investigations have been conducted in recent years to predict the load-bearing capacity of driven piles in cohesionless soils. The problem is extremely complex owing to the large number of factors that affect the ...
