Abstract: This work presents an experimental study of the drag - reduction performance of two water - soluble polymers, Polyacrylamide(PAAM) as flexible, linear synthetic polymer and Xanthan Gum(XG) as a rigid polysaccharide from natural resources. The flow loop used consisted of 0.5 O.D. inch straight pipe with a test section of 3 m length. A 0.5 inch O.D. vertical tubing with elbows was also included to compare the drag - reduction behavior between both tubing configurations. Various concentrations of polymeric additive and water flow rates were tested. The results show that the drag - reduction in vertical piping are significantly lower than in straight type for both polymer type. The dragreduction efficiency of Xanthan Gum agent is much lower than polyacrylamide. Higher concentrations of XG about 150 ppm is required to get exactable drag - reduction performance about 12.84% in the straight pipe. While about 40.3% drag - reduction was achieved with about 50 ppm Polyacrylamide with the same conditions. Moreover, the drag - reduction efficiency of XG can be improved by mixing with Polyacrylamide agent at a given conditions.Part of the experimental work was devoted to study the performance of Polyacrylamide as drag - reducing agent with the existence of small amounts of sodium chloride acts as an inhibitor to the ability of the additive, resulting in lower drag - reduction probably due to collapse of PAAM at more compact structure with the addition of sodium chloride as strong ionic salt.Polyacrylamide and Xanthan Gum additive undergo undesirable mechanical degradation with increasing of circulation time, leading to lower drag - reduction performance. The molecular degradation is likely to occur at low additive concentrations and low turbulence flow, in vertical piping, since the polymeric additives are exposed to shear stresses.Further attempt was done in present investigation to find correlations for accurately predicting drag - reduction characteristics of drag - reducing agents, used in published works. A published time scale hypothesis for prediction of drag - reduction values, the friction factor data as a function of the polymer concentration, shear stress, Reynolds number, pipe diameter. The experimental friction factor results were taken from a published work for gas oil with polyisobutylenes. Good agreement between measured and predicted friction factor. Further attempt was made to correlate the mechanical degradation ability by modifying the Kouraush, Williams and Watt (KWW) equation. The experimental data were taken from a published work for Polyethylene Oxide. The modified equation was found to fit experimental data better than the original KWW equation.

A rotating cylinder electrode (RCE) system were used to study the potentiostatic polarization experiments, under turbulent flow conditions, using 3.5wt% brine solution as electrolyte at different temperatures (298, 308, 318 and 328)K and rotating speed of (0, 100, 200, 300 and 400)r.p.m. at each temperature.Similar experiments were carried out in 3.5wt% brine solution using CO2 gas at (32 ml/sec) flow rate.Corresponding experiments by weight loss were carried out in 3.5wt% brine solution with compunds of : - 1. Kerosene + 10V% brine solution.2. Gas oil + 10V% brine solution. At 328Kand flow rates of (0 and 400) r.p.m.3. Similar experiments were carried out in kerosene + 10V% brine solution at (298, 308 and 318)K and static condition speed of (0) r.p.m at each temperature.4. Experiments were carried out in pure kerosene at a temperature of (298 and 318) K and speed of (0) r.p.m.All above experiments were carried out with and without CO2 gas.The results indicated that the corrosion rate of carbon steel was increased in presence of CO2 gas.The anodic dissolution kinetics were activation control processes affected by temperature.The activation energy of carbon steel with CO2 gas system (2.87 - 1.8) Kcal/mol at different r.p.m. was lower than that without CO2 gas system of (11.4 - 1.7) Kcal/mol at different r.p.m.The corrosion potentials without CO2 gas were shifted to the noble direction with increasing flow rate at a constant temperature, whereas such potential were shifted to the less noble direction with increasing temperatures at a constant speed. However, the corrosion potential with CO2 gas was more noble than that obtained without CO2 gas.The corrosion rate is increased with increasing temperature and velocity. The results indicated that the corrosion rates of ( gas oil +10V% brine solution ) are higher than that of (kerosene +10 V % brine solution) with and with out CO2 gas, and the corrosion rate of pure kerosene is lower than that of (kerosene+10V% brine solution) with and without CO2 gas.In the presence of CO2 gas the results indicated that corrosion rate increases due to continuous dissoultion of iron ion and formation of weak carbonic acid. The carbonic acid accelarteed corrosion rate and affected carbonate and hydrogen ion, which increased the cathodic reactions on the metal surface.

Earth tubes have been used as one of the most widely used heat transfer enhancement techniques in several industrial applications. Earth tube heat exchanger is a device which permits transfer of heat from fluid to deeper layers of soil and vice versa.The results of the heat transfer characteristics in earth tube heat exchanger are presented. The experimental test section is made of 50 m carbon steel pipe of 19.05 mm inner diameters and 25.95 mm outer diameters. The pipe was buried 2 m deep below ground surface. Water and gasoil were used as working fluids in the experimental runs. Experiments were performed under conditions of volumetric flow rates ranging from 0.5 to 2 m3/h and inlet working fluids temperature is between 35 to 70?C at winter season and between 50 to 70?C at summer season. Working fluids temperatures were measured at five points with equal length by thermocouples placed inside the pipe. Also, soil temperatures were measured at these points by thermocouples placed 0.5 m apart from pipe. The effects of working fluid flow rate, inlet temperature, pipe length on the overall performance of the earth tube heat exchanger was investigated at winter and summer seasons, respectively.It was shown that the heat transfer rate of the working fluid increases as the pipe length and inlet temperature increase, or volumetric flow rate decreases. Furthermore, the heat transfer rate in the first half of the pipe represents (33.3 to 87.5%) from the total heat transfer rate, depending on working fluid operating conditions. Also, it was noticed that the heat transfer rate in summer days is less than in winter days. Coefficient of performance (COP) analysis was also carried out to characterize the system performance at different operating conditions. The experimental earth tube heat exchanger (ETHE) system was attained a maximum COP of 45.589 at winter tests and 17.818 at summer tests for water as working fluid. But, the maximum COP was reached only 28.52 for gasoil as working fluid at summer.
