In this study, the results of a direct numerical simulation of turbulent drag reduction in a channel flow by hydrophobic coating at a nominal shear Reynolds number of Reτ = 180 are reported. Slip condition is imposed on the lower wall whereas the upper wall has no-slip condition. For this purpose, the use is made of a numerical simulation of three-dimensional, time-dependent Navier-Stokes e...

Chest wall surgery is a new specialty, which comes from the traditional thoracic but it has characteristics. Because chest must consider appearance of wall, can be regarded as plastic surgery. In addition, because every kind disease involves changes bony structures also orthopedics. The concepts and orthopedics have injected thinking into played positive role in its final healthy development. T...

Thrust chamber cooling system is an important issue in liquid missile systems. In this paper, two more applicable systems, that is, regenerative and radiation cooling systems are studied. Regenerative cooling systems, which are mostly used in high pressure thrust chambers, are normally in two forms, tubular wall structure and double wall structure. Tubular structure has mostly a square form str...

ABSTRACT Among the causes of ascites, there is two kinds, including cirrhotic and malignant ascites that conventional diagnostic method for them is Paracentesis. This method is invasive and time consuming, however sonography is an easy and available method for providing valuable results in a short period of time. The aim of this study is survey of valuability of gallbladder wall so...

Introduction: The horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (PSAa) and the infraorbital artery. This anatomic structure is known as the ‘alveolar antral artery’.   Materials and Methods: We performed a literature review. The anatomic location of the alveolar antral artery in the latera...

abdominal wall hernias are common problems found in patients with cirrhosis because of persistently high intra-abdominal pressure. when abdominal hernias are neglected in such patients, they may become larger and could result in cosmetic problems and pressure effects that are also difficult to treat. we found a voluminous mass in the anterior abdominal wall of a 40-year-old patient with cirrhos...
