1.2 Review papers and books
The following papers summarize the various previous studies, e.g. experimental investigation on impact of PHP parameters on the performance and unsolved issues. The book written by Prof. Ma is the only one dedicated to PHP, as far as Naoko knows.

1.3 Studies on PHP parameters (configuration and working fluid)
As mentioned above, a lot of experimental studies have been conducted to investigate the effects of changing the PHP configuration (shape, number of turns, pipe diameter, inclination, and check valves) and working fluid on thermal performance. Here are some of typical papers:

1.5 Analytical model
A widely used model is based on the one proposed by Shafii et al., which solves the conservation equations of mass, momentum, and energy of vapor plugs. Miyazaki et al. presented other model that expresses the oscillating displacement of liquid slug by a wave equation.

 1.6 Aerospace application
So far, PHP has been mounted in satellites twice, both of which are Japanese ones. The first was launched in 2002 and the PHP operated successfully in the space, but then it failed. The second was launched in 2012 and the PHP operated for 4 years continuously.
