geometries which are found in heat

exchanger applications have been investigated. The

distribution of volumetric local entropy generation rate

resulted from exact velocity profile has been drawn for

selected geometries. Results...

. Adaptation of the results of these

techniques depends on the used velocity profile. Results express that in experimental

works, whatever the values of local and overall entropy generation rates are close to each

other, the results...

A number of equations have been proposed to determine the dispersion coefficeint of stream since 1950.
