Because of smallness of non-diagonal elements of Onsager's matrix, it is proposed to use preliminary transformation of Onsager's equation system to heat conduction equation system. The last system can be solved by any relevant numerical method usually using for solution of heat conduction equation....
The relative amounts of one heat pipe leak valve leakage condition monitoring method, after the first measurement method strengths valve tube pipe working fluid temperature, fluid temperature t01 valve before and after the valve ambient temperature around the pipe, and then use the following formula...
Method for measuring the speed of a gas flow For measuring the speed of flow of a gas stream through a large pipe or duct (1) at least one pipe (2,3) projects into the duct and an opening (4,5) of said duct is oriented such with respect to the central axis of the duct (1) ...
AN INVERSE FINITE-ELEMENT TECHNIQUE TO DETERMINE THE CHANGE OF PHASE INTERFACE LOCATION IN ONE-DIMENSIONAL MELTING PROBLEMS A“front-tracking” finite-element method has been developed for the study of inverse one-dimensional conduction heat transfer problems with phase change...

aall the thermal resistances in the path of heat flow from one fluid to another are combined into a single resistance [6], and an overall heat transfer coefficient, U, of the heat exchanger is determined. 所有热变电阻在热流道路从一流体到另一个被结合入唯一抵抗(6),并且一个总传热系数, U...
In this work, a room-temperature rubbing method is developed for the rapid transfer-free production of defect-free polycrystalline graphene on rigid and flexible substrates. Starting with inexpensive commercially obtained graphite powder, mono- and few-layer graphene can be fabricated directly on ...
