Transient and dynamic performance of solar driven multiple effect distillation

  Transient and dynamic performance of solar driven multiple-effect distillation (MED) system without thermal energy storage (storing of water rather than energy) are studied and presented. A typical 25,900 m3/day operational multiple effect distillation with thermal vapor compression (MED-TVC) is used for the transient and dynamic simulation. Two scenarios are studied for the transient performance to; i) pump...

Modeling of connection elements in static and dynamic analysis

  This paper presents the proposal of a new linear finite element that can substitute for the three dimensional finite model. A study is conducted on a simple frame at the beginning in order to proceed to the crankshaft. First, a three-dimensional model is constructed, then an equivalent two-dimensional model. At a final stage, the results from static and dynamic analyses of many linear element models were...

Effect of heat treatment on dry sliding wear of titanium-aluminum-vanadium (Ti-6Al-4V) implant alloy

  Titanium and its alloys have very attractive properties that enable them to be used in the fields of aero space, biomedical, marine and also in many corrosive environments. The application of these alloys is more attractive today in the field of biomedical implant materials due to their superior biocompatibility and strength. These alloys have high coefficient of friction and poor abrasive wear resistance...
