In this study, the numerical analysis of turbulent flow and heat transfer of double pulsating impinging jets on a flat surface has been investigated. The unsteady two-dimensional numerical solution for two similar and dissimilar jets was performed using the RNG k-ε model. The results showed that the RNG k-ε model has more satisfactory predictions of the Nusselt number distribution. Comparisons ...

Introduction: The inferiorly and laterally based platysma myocutaneous flap contains hair in some ethnics; therefore, it is required to change the myocutaneous flap to myofascial flap to prevent the hair growth after its transfer to the oral cavity.   Materials and Methods: Five male mongrel dogs were selected for this study. De-epithelialized laterally based platysma fl...

BACKGROUND AND PURPOSE Concern exists that vertebral bodies augmented with cement placed laterally may be at risk of collapse on the nonaugmented side. The purpose of the current study was to determine if placing the cement laterally rather than centrally resulted in risk of collapse on the nonaugmented side. METHODS Vertebral bodies (L2-L5) were harvested from eight osteoporotic female cadav...

In a laterally asymmetric intake pumping station, the flow direction in forebay is not consistent with channel. Thus, adverse patterns, such as bias flow, large-scale vortex and occur frequently sump. Based on Reynolds-averaged Navier-Stokes (RANS) equation RNG k-ε turbulence model, recent pattern station was numerically simulated analyzed, effective elimination measures were proposed. For orig...

Modeling transport, erosion, and deposition of nonuniform sediment over temporal intervals that are short compared to those characterizing channel bed aggradation degradation remains an open problem due the complex quantification fluxes between material load alluvial deposit. Parker, Paola, Leclair in 2000 proposed a morphodynamic (PPL) framework overcome this problem. This is used here model d...
