Abstract:

Increasing the thermal efficiency in newly designed power stations is a priority. Keeping the efficiency in existed plants close to the rated one is of paramount importance. This research contributes to investigating the adverse effects of changes in condenser seawater coolant characteristics, (temperature, fouling, and salinity), on the thermal performance of a Boiling Water Reactor Nuclear...

Abstract:

Jetting succeeded by accumulation is the characteristic of the vacuum filling, which is different from the conventional pressure-driven flow. In order to simulate this kind of flow, a three-dimensional theoretical model in terms of incompressible and viscous flow is established, and an iterative method combined with finite element method (FEM) is proposed to solve the...

This article aims to examine the behavior of Unplasticized Poly- Vinyl-Chloride (UPVC) bounded reinforced columns with polypropylene fibers under axial compression. To develop this model, a no samples of concrete filled UPVC pipe (CFUT)  with different geometric properties were tested. To obtain the specimens different class pipes with three different diameters were used to investigate the...
