Mhd flow and heat transfer of two immiscible fluids between moving
Mhd flow and heat transfer of two immiscible fluids between moving

... flow of electrically conducting fluids in channels and various geometric elements is required. From this lesson learned; most recent research activities tend to refocus to basic and simpler fluid dynamic-electromagnetic interaction phenomena. All the mentioned studies pertain to a single-fluid model ...

... figure. Integrating Cm/T between 1.8 K and 60 K, we find a value of 4.1 J/mol K which is about 30 % smaller than the total magnetic entropy (Rln2) for S = 1/2. The discrepancy is most likely due to crudeness of the estimation of the lattice contribution particularly at high temperature. To be noted ...

Time in physics



Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
