When the temperature of the external surface of a wall increases, it is important to predict what the thickness of the wall will be so that the internal surface of the wall does not exceed a limit value. We will study, by an analytical method, the ca
se in which the external surface temperature is linearly varying with time in order to determine the time for which the temperature does not exceed a predetermined limit value at a given depth from the surface. Two cases will be considered: the first one is for a wall made of a homogeneous material (e.g. concrete) and the second one is for a wall made up of concrete and phase-changing material whose melting temperature will be selected according to the desired temperature. The results obtained show that a significant delay to reach this temperature can be obtained between the two cases.
This research aims to decrease the cost of last production stages
through decreasing the cost of potential casing repair by avoiding the
problems that casing string may be exposed to. Such problems are
caused by the temperature effect of salt dril
ling fluids as well as other
fluids normally existed in the annular behind casing at the nonecemented
intervals.
The main objective of this research is to estimate the potential electrical power that can be extracted from closed and out-of-service oil wells situated in the north-eastern part of Syria. The research shows that using Organic Rankine Cycle (ORC) wi
th Isobutane as working fluid can produce net power output under certain conditions. The geothermal cycle used brine solution to
absorb the ground heat.
This study is devoted to the durability of bituminous mixtures,
including the effects of different gradations, compaction
temperatures and immersion time on the durability potential of
mixtures.
The research aims to study the effect of of agar extraction
temperature (80-90- 100-110 and 120) Syrian alga Pterocladia
capillacea on its yield and and some physical properties.
