Ducts are often used in reactors and heat exchangers. Using rough surfaces in ducts is recognized as an effective technique to enhance heat transfer. In this research, an entropy generation analysis is carried out for turbulent flow inside a ribbed...

infiltration breakthrough (RIB) methods were selected to estimate

the groundwater recharge. These methods are based on

the water balance principle (rainfall–groundwater level relationship)

and require few non-deterministic data such as...

The thermo-hydraulic behavior of the air flow through a solar air heater is numerically simulated and then optimized by use of Taguchi method. An innovative general geometry is introduced for the rib that variation in its parameters can generate...

equation to predict the bond strength has been modified to account for the effect of rib properties of reinforcing bars. Also, a new parameter to account for the effect of transverse reinforcement on bond strength has been introduced. The comparison between...
