Variant Developments of Typical Meteorological Years (TMYs) for Seeb, Oman and their Impact on Energy Simulation of Residential Buildings

Nasser Ahmed Al-Azri, Saleh Nasser Al-Saadi · The Journal of Engineering Research · 2018 · 10.24200/tjer.vol15iss2pp129-141

Typical meteorological years (TMYs) are widely used for the analysis and simulation of energy-intensive systems. The reliability of a developed typical year depends on the accuracy of the historical record of weather data as well as the fitness of the developed approach to the application. In this work, a TMY for Seeb …

Estimating Drilling Cost and Duration Using Copulas Dependencies Models

M. Al Kindi, Mohamed Al-Lawati, Nasser Ahmed Al-Azri · The Journal of Engineering Research · 2017 · 10.24200/tjer.vol14iss1pp1-9

Estimation of drilling budget and duration is a high-level challenge for oil and gas industry. This is due to the many uncertain activities in the drilling procedure such as material prices, overhead cost, inflation, oil prices, well type, and depth of drilling. Therefore, it is essential to consider all these uncertai …

Prediction of Hourly Solar Radiation on Horizontal and Inclined Surfaces for Muscat/Oman

Nabeel Z. H. Al-Rawahi, Yousef H. Zurigat, Nasser Ahmed Al-Azri · The Journal of Engineering Research · 2011 · 10.24200/tjer.vol8iss2pp19-31

In this paper, hourly terrestrial radiation: direct beam, diffuse and global solar radiation are modelled and calculated based on daily measured data for a horizontal surface. In addition, the same parameters were modelled for inclined surfaces. Most of the parameters modelled in this work represent a part of the input …
