When internal conduction resistance is much smaller than the thermal resistance for heat transfer from its surface, a solid body may be assumed to be at the same temperature throughout. The solid body is treatable as a lumped system. Similarly, a volume of liquid/gas may be considered to be...
Also, the heat transfer inside the system and heat losses to the atmosphere are considered using the principles of conduction, convection, and radiation. The parameters related to the dynamics of moving wire are also designed. The designed furnace is fabricated and tested for its working, the ...

This case study shows that the MLP-BFGS model is better able to adjust its weights to estimate fluoride concentration in the groundwater system. This agrees with some other studies, where MLP-BFGS can be reliable in many groundwater problems, e.g., Li and Liu (2005). View chapter Book ...
A numerical approach on the use of heat storage in order to achieve high EGR rates in cold-climate conditions 3 Numerical Model Presentation The complete system is modelled using LMS software AMESim. A lumped-mass model is used to simulate the engine thermal behaviour. It is composed of a to...

Simultaneous heat and mass transfer, during drying of moist capillary porous media, is modeled through different lumped-differential formulations, obtained from spatial integration of the original set of Luikov''s equations for temperature and moisture potential. Besides the classical lumped system ...
