“…It was further reported that the impulse fluctuated from 30 N•s up to 98.5 N•s for its 4s run at 1 Hz frequency. The average force was 61.5 N [17] which is in line with reports from similar research. In this PDE, as in many, there is a purge phase after the detonation that clears the PDE of exhaust gases and cools it as well.…”

With the constant drive to improve the efficiency of systems used to generate heat and work pulse detonation engines have been explored. Pulse detonation engines can be described by the Humphrey thermodynamic cycle which, in theory, has advantages over the Brayton, Otto, and Diesel cycles. This work is concerned with the design, fabrication, and the initial tests of a pulse detonation laboratory test bed. The test bed was designed with modularity and ease of alteration in mind while ensuring that a wide range of detonable fuel and oxidizer mixtures where able to be utilized. Initial testing with a methane and oxygen mixture showed repeatable detonations in both single shot and cyclic operating modes. The expected detonation velocity was 2390m/s. Detonation was monitored with ionization probes and detonation velocities of 2391m/s were found as close as 30" from ignition source and some form of detonation as close as 6" from the ignition source.

The hottest issue toward the environment today is the Clean Development Mechanism (CDM) and Green House Gases (GHG) which influenced climate change. At the same time, the world is facing the crisis of limited reserves of petroleum-based fuel resource which is being continuously depleted. Therefore, these three issues can possibly be overcome by using alternative fuels such as biogas, biodiesel, biomass, biofuel, alcohol, vegetable oils etc. The use of biogas as fuel for Pulse Detonation Engine (PDE) possibly promise great advantages on power production with less emission. This is because PDE operates with higher thermodynamic efficiency by operating on constant volume pressure. Biogas usage will somewhat contributed to the CDM and and lessen the GHG issues. Here through detailed literature review, the challenges such as lower flame speed (compared to hydrocarbon fuel) and biogas impurities are discussed. Combustion characteristics of biogas in detonation mode are also investigated. Strategy is presented here for looking at the possibility of PDE operation using biogas.

The Pulse detonation Engine (PDE) research program has been started at High Speed Reacting Flow Laboratory (HiREF), Universiti Teknologi Malaysia (UTM) since 2005. The studies began with a single pulse detonation study for detailed investigation of detonation characteristics of various fuels and followed by development of repetitive PDE engine, performance study and augmentation of thrust using various types of ejectors. This paper summarizes the laboratory facilities, research activities conducted and the output from all of the related research programs.
