Abstract: In comparison with a kinematic wave–based equation for estimation of the time of concentration, three methods, Ben-Zvi’s method, the modified Ben-Zvi method, and Izzard’s method, were applied to determine the time of ...

Abstract: Abstract. Good dynamic characteristics are essential for the safe operation of noncontact mechanical seals. This article investigates a diffuser-type self-pumping hydrodynamic mechanical seal (DSPHMS) by integrating the ...

Abstract: An improved volume of fluid method called the accurate density and viscosity volume of fluid (ADV-VOF) method is proposed to solve two-phase flow problems. The method has the following features: ...

Abstract: Heat transfer characteristics for condensation for R410A inside horizontal round (dh = 3.78 mm) and flattened tubes (aspect ratio (AR) = 3.07, 4.23, and 5.39) with larger horizontal than vertical dimensions at a saturation ...

Abstract: Abstract The mesodeformation characteristics of the frozen soil–concrete interface are of great significance for revealing the mechanism of shear damage evolution, which directly affects the stability and durability of ...

Abstract: Novel fiber-reinforced polymer (FRP) bar-reinforced ultrahigh-performance engineered cementitious composites (UHPECCs) have been proposed recently. This innovative composite structure aims to address two critical challenges: ...

Abstract: Abstract In this study, the pressure-cast-in-situ pile with spray-expanded frustum (PPSF) was proposed to increase pile bearing capacity, reduce pile settlement, and improve construction speed. The construction process of ...
