The Oberbeck--Boussinesq Approximation as a Constitutive Limit

, 2015
We derive the usual Oberbeck--Boussinesq approximation as a constitutive limit of the full system describing the motion of an compressible linearly viscous fluid. To this end the starting system is written, using the Gibbs free energy, in the variables $\

Achieving excellent comprehensive thermal performances in (GF+CF)/(Cu+Ti) composites via hybrid reinforcement strategy and highly oriented structure

Journal of Materials Research and Technology
Although graphite flakes (GF)/Cu composites have high thermal conductivity (TC) in the basal plane direction of GF, the problem of high coefficient of thermal expansion (CTE) makes it unable to meet the requirements of thermal management.
