absorption cooling systems </span> <span style="font-size:10pt;">where heating, pumping of the binary solution,
and the separation occur </span> <span style="font-size:10pt;">. The existing
theoretical models of the bubble pump were initially developed for air lift
pumps where neither heating nor separation occurs. Thus, the experimental
results for a bubble pump did not correlate well with the theoretical models.
Empirical values were suggested in some of the models; however, their values
varied from one system to another and could not be predicted analytically. In
this work a modified model based on mass, energy, momentum, and heat balances
is presented with the utilization of the drift flux model with laminar flow assumption.
In addition, for the first time the applied heat is expressed in the model. The
suggested model fits better with the experimental results than the previous
models. </span> <span style="font-size:10pt;"> </span> </p> <p> </p>}, number={4}, publisher={Uluslararası Uygulamalı Termodinamik Derneği İktisadi İşletmesi}
