Improving the energy efficiency and carbon dioxide reduction of a long-haul bus through aerodynamic design optimization

by Sunil S. Arunachalam K.

Issue 5

Climate change

Exhaustion of fossil fuel resources, inconsistent fuel costs and the difficulty of adopting electric vehicle technology in commercial vehicles support the idea that there is an opportunity for research in public transit regarding the correlation between energy efficiency and aerodynamic drag. The...

Issue 1

Environmental Sciences

Three-dimensional numerical simulations, performed using the MIKE 3 FM (HD) code, have been used to study the effect of a severe wind event on the early stratification structure in the Gulf of Patras, Greece. Before the onset of the severe wind event thermocline was at an approximately mean depth of...

Issue 1

Hydrology and Water Resources Management

Groundwater is one of the major parameters in maintaining ecology in many regions. As climate is one of the main factors which affects groundwater resources, the main objective of the present study is to assess the impact of rainfall changes on the groundwater system by projecting the future changes...

Modeling renewal times in Amvrakikos Gulf, Greece

by

Stamou A.I., Loverdou L., Matsoukis C., Albanis T. and Gkesouli A.

Issue 3

General

The Amvrakikos Gulf, located in the northwest Greece, is one of the largest semi-enclosed embayments being about 40 km long and 15 km wide. Water renewal is made via a narrow channel which connects the Gulf with the Ionian Sea having a 3.0 km length, width ranging from 0.8 to 2.0 km and depth from 2...

Optimization of the furrow irrigation efficiency

by

Ampas V. and Baltas E.

Issue 4

General

Furrow irrigation is used for row crops. S.C.S., based on a great number of field experiments, under different circumstances and soil families, has developed design equations for furrow irrigation. These equations have been used for steady flow rate or for flow rate with one reduction when the water...

Biological treatment of water contaminated by hydrocarbons in three-phase gas-liquid-solid fluidized bed

by

Allia K., Tahar N., Toumi L., and Salem Z.

Issue 1

General

Biological treatment has been carried out in two different systems: aerated closed and threephase fluidized bed reactors for hydrocarbons removal from refinery wastewaters. For the two systems, hydrodynamic study allowed the determination of operating conditions before treatment experiments. Then...
