Pressure drop characteristics of turbulent flow through 90 degree pipe bends are numerically investigated by computational fluid dynamic simulation using k-ε RNG turbulence model with standard wall function. After the validation of present model against existing experimental results, a detailed study has been performed to investigate the pressure distribution and pressure drop characteristics o...

New fluid states of matter, now known as liquid crystals, were discovered at the end 19th century and still provide strong themes in scientific research. The applications crystals continue to attract attention, most successful so far has been technology flat panel displays; this diversified recent years LCDs no longer dominate industry. Despite this, there is plenty more be uncovered science we...

Bridges when it crossing rivers often required multiple piers for support. One of has a limited investigation is the impact on scouring and morphological aspects bridge sharp-bend river. Consequently, crucial to investigate hydraulic behavior water flow in these areas due presence piers. In present study, an experimental program was conducted laboratory flume featuring two-pier within 180-degre...

Contemporary electronic cooling applications can feature complex heat pipe configurations with multiple sources (MHSs) and one or more bends in various locations to meet physical constraints. It is typically understood that implementing a bend adding MHS was tested for straight single source (SHS) degrade thermal performance. However, the severity of combining two phenomena effects changing loc...

In this work, results are given for controlling waves arbitrarily inside a lattice with spatially variant self-collimation. To demonstrate the concept, an unguided beam was made to flow around a 90◦ bend without scattering due to the bend or the spatial variance. Control of the field was achieved by spatially varying the orientation of the unit cells throughout a self-collimating photonic cryst...
