Pipe Flow: Research and Applications, 2nd Edition

Dear Colleagues,

The flow of fluids through pipes is an engineering problem of long-standing practical importance, with applications ranging from household water and gas supply to sewage flows to the transportation of chemicals and petroleum in the chemical and oil industries. It is also currently used in numerous heating and cooling applications.
The first scientific studies on pipe flow began to appear in 1839, when Hagen and then Poiseuille performed the first experiments on water flow through straight pipes of various sizes to determine pressure losses. Later on, Reynolds, in 1883, observed that the transition from Hagen–Poiseuille (i.e., laminar) to turbulent flow in pipes occurs above a certain critical value, known today as the critical Reynolds number. Since then, pipe flow has received particular interest as a gateway to turbulence, not only at high Reynolds numbers in straight pipes but also at relatively slower flows through pipe elbows, bends, and restrictors.

While experimental work on pipe flow has continued until the present day, from the beginning of this century, there has been renewed interest in the investigation of pipe flow due to the emergence of ever more sophisticated numerical techniques and increased computational facilities. Many numerical flow models exist in the literature that have improved our knowledge of what happens inside a pipe for both single and multiphase flows. Numerical work has become of great importance not only to interpret experimental data but also to predict, under certain conditions, the resulting flow pattern. This aspect has been particularly important for complex multiphase flows where transitions to one or more flow patterns may occur. Topics of interest for this Special Issue include the following: biofluid dynamics involving the study of the motion of biological fluids, as blood flow in arteries and respiratory airflow, non-Newtonian pipe flows and applications to microfluidic devices, spiral and helical coil tube heat exchangers for cooling and heating applications, ventilation and air conditioning, among other problems and applications. This Special Issue, entitled “Pipe Flow: Research and Applications”, is devoted to collating recent advances in experiments and numerical simulations of fluid flow in pipes of different cross-sectional shapes as well as geometries.
