A study was carried out to determine in-tube evaporation and condensation performance of enhanced heat transfer tubes (EHT) using R410A, with the results being compared a plain tube. The test considered in evaluation include: plain, herringbone (HB) spiral (HX) microgrooves, dimple (HB/D), hydrophobic (HB/HY). Experiments evaluate were conducted at saturation 318 K, 279 K for evaporation. Mass ...

This paper addresses the issue of multimedia cooperative work. An ODP based view of the system is discussed taking into account some of the viewpoints of the standard. Special emphasis is given to the modeling of multimedia stream interfaces and the concept of binding object which is a key concept. The paper describes a multimedia distributed platform, DIMPLE, supporting interactive and distrib...
