Integrating cooling systems with photovoltaic-thermal (PVT) collectors has the potential to mitigate exergy consumption in building sector due their capability for simultaneous power and thermal energy generation. The utilization of nanofluid geometry modification resulted a synergetic enhancement performance PVTs thereby reducing sizes costs. In addition, there is still lack high accurate predictive model estimation at given Re number concentration ratio be used engineering design further...
Time synchronization plays an important role in UANs, which need fine-grained coordination among nodes. Precise time is also needed for a variety of other coordinate tasks UANs such as data fusion, TDMA scheduling, localization, power-saving and so on. Recently, protocol point-to-point with high propagation delay has been proposed, while multi-hop still open issue. In this paper, we propose scheme Underwater Acoustic Networks (MSUAN). MSUAN includes three stages. the first stage, assign each...
In order to realize energy saving and high-efficiency production in the CNC turning process of parts, a novel hybrid approach for cutting parameters' optimization considering processing efficiency is proposed. Through experimental fitting orthogonal experiments, no-load power functions lathe were obtained, multi-objective model high was established. The takes minimum consumption fastest time as goal, comprehensively considers actual constraints under conditions lathe. An improved...
As the air-side heat transfer is controlling efficiency of finned tube exchanger (FTHX), this makes its enhancement important. After analyzing thermal hydraulic performance conventional plain plate fin, two novel fin configurations are proposed. The first design guides more airflow into back tubes and eliminates wake zones. second significantly enlarges area with little pressure drop penalty. Numerical investigations designs conducted. Based on temperature velocity flow fields Nusselt number...

Cold air by-pass and hot recirculation are two primary sources of inefficiencies in data center thermal management. Although some studies have been conducted to investigate the cause such issues [1] [2], few attempts were reported improve situation by changing rack layout configuration. A new layout, called Vortex Flow Layout (VFL) configuration is proposed this study. The simulated under fully, partial no containment cases evaluate its performance. Studied from a steady state CFD model...
This paper presents a numerical investigation of air-side performance novel design finned tube heat exchangers (FTHX) with oval obstacles located along the circumference refrigerant tubes (constant-temperature source) for enhancing thermal and hydraulic condenser.

Based on realizable k-ε...
Plate fin and tube heat exchangers (FTHX) are widely used in HVAC applications due to the high effectiveness cost ratio for transfer between two fluids. For air-cooled residential air conditioning unit applications, overall efficiency of is limited by air-side coefficient, which much lower than that refrigerant-side.
