Abstract
The presented thesis aims to study the
performance of heat pipe engine with two cylinders.
One of them is the driver for the other one to be an
integrated engine. The presented work also aims to
mathematically model the heat pipe engine for
simulating its performance. The thesis is divided into
two integrated parts: The first part treats design,
manufacturing, and operating the engine with R11 as a
working fluid. A computerized data acquisition system
is attached to the engine to detect the performance.
, The second part concerns the deducing of the
governing mathematical relations from the
thermodynamics and kinematics point of view. These
relations are put in a form a computer program for
simulating the engine performance. The main
results of the presented thesis are fulfilled by
accepting the mathematical model after comparing its
output results with both the experimental and
published one. Also, the fruitful result is that by
increasing the charging mass in the engine, the
amount of mechanical output work increases while the
overall efficiency of the engine decreases.
