Article
A simple and workable design of solar distiller (SD) targeted for a household potable water requirement is presented. The efficacy of the SD is tested using seawater taken from the Ad-Dahariz region in Salalah, Oman. The water samples were tested for chemicals and biological activity before and after using the SD. The results revealed that the samp...
Article
Improved design of simple solar desalinator was fabricated for the conversion of seawater into potable water. The efficiency was calculated by using samples of seawater collected from Ad-Hariz region-Salalah-Oman. It was found that the samples contain minerals of very high concentrations and no bacteria presented. The average %efficiency was 16.063...
Conference Paper
Adsorption followed by filtration technic was used for removing heavy metals (Cu, Zn, Mn, and Cr) from the polluted water. Three types of soils (silty, sandy and clay) and three types of marble powder (pure, impure, marble-granite mix) were used as an adsorbent. The soil and marble samples were collected from different regions of Oman. The maximum...

Conference Paper
Practical simple new solar desalinator (SD) was designed and fabricated to convert seawater into potable water. Its efficiency was tested using seawater taken from Ad-Hariz region-Salalah-Oman. The results showed that the samples contain minerals of very high concentrations and no bacteria available in them. We found that the average %Efficiency wa...

Boil-off gas (BOG) from a liquefied natural gas (LNG) storage tank depends on the amount of heat leakage however, its assessment often relies on the static value of the boil-off rate (BOR) suggested by the LNG tank vendors that over/under predicts BOG generation. Thus, the impact of static BOR on BOG predictions is investigated and the results sugg...

Article
The simulation of liquefied natural gas (LNG) storage tanks is often based on several problematic assumptions, for instance, estimation of boil-off gas (BOG) generation using boil-off rate, vapor-liquid equilibrium in the tank, static liquid level, the use of only lateral area for heat loss calculations, and etcetera. Some of these assumptions are...

Theoretical calculations were done using (EMTs) and character matrix method. Bruggeman theory gives better fit than Maxwell-Garnett theory. The behaviour of the reflection measurements (R) as a function of wavelength was found to be the same for both theories. The absorption increased greatly over the solar range and slightly over the infra-red ran...

Without frequent cleaning, dust accumulation on parabolic trough collectors can lead to significant degradation of the performance of trough collectors over time. Owing to the nature of the trough profile and the presence of the receiving tube in the middle of the trough, automatic cleaning has not been a feasible option. The problem of dust accumu...
