“…Many researchers has developed mathematical models of the coupled heat and mass transfer processes in the ACS or regenerator, and most of the models were solved numerically [17], [18]. In this part, we present a schematic model and an analytical solution of heat and mass transfer processes in the principal components of a liquid desiccant cooling system.…”

“…Fig . 5 shows the desiccant solution cycle process on Chart of equilibrium between the vapor pressure of aqueous solutions of lithium chloride and the partial pressure of water vapor in the air, at the normal sea level atmospheric pressure [18]. Before entering the regenerator, the weak desiccant solution (point 1) is heated by a hot water coming from the heating system (point 2), which the water vapor is removed from the weak desiccant solution to the regeneration air.…”

Abstract-The solar potential energy in Tunisia can be used like a principal factor for the operation of new technologies of air conditioning. Studies could be carried out like approaches of simulation, analyzes experimental or both unit. In this paper, we present an analytical solution of heat and mass transfer processes in regenerator and air conditioning system (ACS) cores of a heat recovery /desiccant cooling system (HRDCS) under Tunisia weather conditions. Simulations programs were carried out to test the principal components of the HRDC system. The results show that the coefficient of performance of system improves when we use the renewable energy for heating and cooling. This study is significant and effective to prove the efficiency of such HRDC systems in this country.

“…This time water was repeated along with tests using a CaCl Brine solution which was approximately 30 % CaCl by volume. Fluid properties for the CaCl Brine were obtained from a report Conde (2009). Tests for both fluids were conducted at all angles for 50 SCFM gas flow and again in the vertical orientation for 25, 50, 75, and 100 SCFM gas flows.…”

An experimental study on bubble (slug) rise inside a pipe filled with static liquid and bull heading of a gas flow with a liquid flow is presented. The bubble rise velocity (BRV) was measured inside a pipe with different inclinations and is compared with two well-known models. The static tests have been performed with three different liquids: water, CaCl brine mixture, and non-Newtonian fluid (Xanvis TM ). A model is proposed, based on the drift flux method, to predict the bubble rise velocity. Dynamic well killing (or top kill) is also examined, whereby a continuous gas flow is suppressed with a counter current liquid flow. Flow tests at different angles from vertical were undertaken to investigate the effect of inclination on the liquid flow rate needed to bullhead the gas flow. A simple empirical model based on the results is proposed to predict the results in actual wells.
