... printing. Numerical investigation on pressure loss and heat transfer characteristics of rectangular channels has been carried out based on the naturally formed rough model. Constant thermal boundary and symmetry boundary conditions were employed in the procedure of numerical computation. For comparison...

.... In this paper, an experimental model (a circular and transparent pipeline, 90 mm in ID and 10 m in length) is used to predict pressure loss in a pipeline or tunnel involving resonance and shock waves introduced by a two-phase air-water slug flow. For this purpose, differential pressure transducers were used...
