(1) Consider a cold plate fabricated from aluminum (k=190W/mK) with regularly spaced rectangular channels through which the water is passed. Using the nodal network shown in the figure and assuming the top surface of the cold plate to be insulated, determine the nodal temperatures.

surface, improved solubility, targeted drug delivery and multifunctionality, nanoparticles have emerged as potential drug delivery carriers to tissues throughout the body. Yet passing the BBB is particularly difficult. The proper design of such engineered ‘nanocarriers’ becomes very important in transversing the impermeable membranes to facilitate drug delivery. At the same time, it is also r

heat transfer coefficient값의 문제점.
Convection heat transfer coefficient가 일정하다고 생각했으나 실제실험에서는 조원들의 움직임이나 실험실 문의 여닫음에 의해서 Forced convection이 일어났을 가능성이 있다. Forced convection이 일어나지 않았다고 생각하더라도 Free convection시에 온도구배에 의해서 실제로 Convection he
