A computational fluid dynamic (CFD) analysis and an experiment on single cylinder engine test bed of combustion process in a compressed natural gas direct injection (CNGDI) engine with compression ratio 14:1 have been conducted by Abdullah et. al. [3], concluding that a proper heat transfer mechanism was needed to avoid engine malfunction.
Simulation was conducted for all engine speeds on three types of pistons namely the uncoated piston crown, tin (Na2SnO3) coated piston crown and ceramic based yttria partially stabilised zirconia (YPSZ) coated .

Along some FSI simulation performed for the reference design shown in Fig.
5 it has been shown, that even for wings with a small span the deflection as shown in Fig. 7 (left)
can be remarkable.
Numeric validation performed has been based on a major simulation environment consisting of CAD, CFD and FE software.
Simulations were performed for a variety of flight conditions and parameters.

To compare the performance between a conventional MAV steered by a rudder and the vector thrust steered alternative an analytic simulation model has been applied which has been described in further detail in [3].

Nore et al. [20] indicates that the proportionality factor, called the incident rainfall coefficient, is a function of the terrain characteristics and of the building itself, and can be determined from experimental results or simulations with computational models of fluid mechanics (CFD).

Wang [8] has verified using CFD simulation and tests that the emitter prototypes and emitter amplifier model designed based on Froude model law have similar pressure-discharge relationship and pressure distribution along the flow channel.
