This experimental work studies the distribution of a two-phase
refrigerant flow over a horizontal impacting T-junction. A setup
was built which consists of two parts: a flow conditioner and
a test section. The flow ...
In this communication, a grooved flat plate heat pipe is considered
with an electric field applied between the top and bottom
plates of the heat pipe. In this way, a dielectric force arises,
which aims at pumping the ...
Mathematical modelling is playing an important role in
providing good understanding of heat and mass transfer in food
processing. It has also been used to assess both microbial and
biochemical changes in foods during ...
The transitional flow regime has been mostly avoided by
designers due to uncertainty and perceived chaotic behavior.
Previous work done in the transitional flow regime did not focus
specifically on the effects of free ...
The dynamic of a sessile droplet spread of a wetting
Newtonian fluid into a porous substrate in the presence of
