Characterization of Black Nickel Solar Absorber Coatings on Brass Substrates

2018
2018 International Conference on Advanced Science and Engineering (ICOASE),Duhok, Iraq
Solar Selective coatings have radiative characteristics which vary with wavelength. They are characterized by their high absorbance (α) in the visible region and low thermal emittance (ε) (or high reflection) beyond the visible region of the sun spectra. These coatings materials are of very great importance in the field of renewable energy sources (solar energy applications). In the present study, the influence of process parameters like the current density, concentration of particles, time of deposition, the thickness of the electrodeposited nickel (Ni), etc. was investigated. The objective of the research is to study solar selective coatings used in solar thermal collectors. i.e. black nickel (B-N) coatings, electrodeposited (ED) over brass substrates. Preparation and characterization of B-N coatings over brass substrates was performed. Low-cost solar selective absorbers (ED of B-N on brass) have been obtained.

Water quality index of the Little Khabur River in Zakho City Kurdistan Region

2015-07
The 7th International Conference of SuDBE2015, Reading, UK; 27-29 July, 2015 (2015).
Little Khabur River is an important watershed in Northwest of Kurdistan region of Iraq. Water quality parameters were sampled from June 2013 to August 2013 covering the dry season at 3 sites at Begin, Middle and End. Seven parameters were included for the Water Quality Index, temperature, total solids, pH, dissolved oxygen, turbidity, total phosphate, and biological oxygen demand measured.

Control of solar heat gain to reduce the energy consumption of buildings in Iraq

2012-05
World Renewable Energy Forum, Denver, CO, USA
It would be advantageous to reduce the energy consumption of buildings to a more environmentally friendly level and to a more energy cost efficient level by using Solar Control Window Films (SCWF). These films help to keep the summer heat out and help to lock the heat inside in winter
