far more general compared to the traditional approaches, providing the designer the flexibility to select the efficiency of the individual heat exchangers, the overall system efficiency, the number of heat exchangers, as well as the type of heat exchanger to select, by utilizing a single equation....
The problem was solved based on a system of one-dimensional (cross-section averaged) energy equations for two heat carriers and the heat conduction equation for the wall. The wall ends were assumed to be heat insulated. The system was solved using the finite-difference technique. For the ...
For the winter period the problem is solved easily by assuming dry heat transfer and using the graphical representations of Kays and London1 and Schedwill2, or the equation given by Schedwill2 for reading or calculating the heat exchanger effectiveness, e d, as a function of the number of ...
The analysis of the effectiveness and efficiency of Vernomia amydalina (VA) solution as an inhibitor on offshore pipeline and Ship materials (Steel) was carried out with the preparation of the specimen and the VA solution. The specimens were kept in a wo
of thermal management, including heat removal for electronic devices, including technologies where thermal management has traditionally been less of a concern, such as CMOS. In particular, the need for faster and more densely packed circuits has had a direct impact on the importance of thermal ...
For this purpose a new model with a water film that flows down, corresponding to the real conditions in these heat exchangers, is developed. The method of Maclaine-cross and Banks is improved by an approach to determine the mean water surface temperature and by derivation of an equation for ...
The proposed model is a gray model that uses mathematical equations that are deducted from the effectiveness and number of the transfer unit of the heat exchanger and a regression equation for the ratio of humidity capacities (X factor) analogous to the heat capacities ratio of heat exchangers. ...
Equations for predicting the axial temperatures as well as the effectiveness of the fluids of a microchannel heat exchanger operating under laminar flow conditions have been developed. In addition, an equation for determining the heat transfer between the fluids has also been formulated. Irrespective ...
Besides an equation-based approach, an easy-to-use psychrometric-chart based approach is presented to determine the performance of an ideal ICHDHMX. We invoke conservation principles to ascertain whether or not it is feasible to use the ICHDHMX for a given set of inlet conditions of air and...
The pilot unit recovered over 60% of sensible heat in the test. In addition, a simplified model of Dry Coil IEC returning the various operation conditions was developed based on existing models of an SHE and a direct evaporative cooler. A polynomial equation returning the effectiveness of the ...
