“…This approach provides a relatively inexpensive and powerful compliment to experimental and field-based testing of energy devices. Numerous techniques have been developed to provide faster and more accurate simulations of complex, multi-physical transport processes arising in solar power cells [1], hybrid batteries [2], magnetohydrodynamic (MHD) pumps [3], electrohydrodynamic (EHD) pumps [4] and other renewable energy systems [5]. Both academic and commercial industrial research in energy systems, which is fundamental to mechanical, chemical, biomedical and materials processing systems, has benefited immensely from the many different computational solvers which have been developed, refined and implemented.…”

SummaryWe study the (R) and axial (X) direction. A numerical finite difference (FTCS) scheme is used to compute the velocity (U,V), temperature () and dimensionless zero moment of intensity (I0) distributions for the effects of conduction-radiation parameter (N), Darcy parameter (Da), Forchheimer parameter (Fs), Rayleigh buoyancy number (Ra), aspect ratio (A) and Prandtl number (Pr). The computations have shown that increasing aspect ratio increases both axial and radial velocities and elevates the radiative moment of intensity. Increasing Darcy number accelerates both axial and radial flow whereas increasing

“…In addition, the widespread emergence of bio-based fuel such as biomass and biodiesel has empowered the adaptation of the microturbines [23][24][25][26]. Comprehensive analysis of some microturbine behaviors such as turbine ramping times, ramp-up and ramp-down times during load changes is reported by Robert [27].…”

“…The thermal performance prediction of gas turbine engines operating with biodiesel has barely been reported in References [25,26] using these computational techniques. The opposite is true for reciprocating engines operating with biodiesel blends, for which performances and emissions predictions have been extensively carried out.…”

Instead of simplified steady-state models, with modern computers, one can solve the complete aero-thermodynamics happening in gas turbine engines. In the present article, we describe a mathematical model and numerical procedure to represent the transient response of a PT6A gas turbine engine operating at off-design conditions. The aero-thermal model consists of a set of algebraic and ordinary differential equations that arise from the application of the mass, linear momentum, angular momentum and energy balances in each engine’s component. The solution code has been developed in Matlab-Simulink® using a block-oriented approach. Transient simulations of the PT6A engine start-up have been carried out by changing the original Jet-A1 fuel with biodiesel blends. Time plots of the main thermodynamic variables are shown, especially those regarding the structural integrity of the burner. Numerical results have been validated against reported experimental measurements and GasTurb® simulations. The computer model has been capable to predict acceptable fuel blends, such that the real PT6A engine can be substituted to avoid the risk of damaging it.
