The gas turbine is one of the most suitable equipment for various applications. Usually, a gas turbine comprises a set of discs to maintain turbine blades. The rotating disc in gas turbines is one of the critical components affected by various thermal and mechanical loads. The current article considers a new rotating disc with variable thickness (power-law profile). The functionally graded material has been used as the disc material, and the disc’s properties vary with temperature and location. Therefore, the mechanical and thermal behaviours of the disc are a function of temperature and location. The differential energy balance equation has been derived for analysing the new disc. In the performed analysis, the conduction and convection heat transfer coefficients vary with temperature and location; thus, the derived final heat transfer equation has high nonlinearity. One of the efficient expansion methods, the so-called Differential Transformation Method (DTM), is used for the governed equation’s analytical solution, and the numerical solution is used for validation. Then, the stress analysis is performed using analytical expressions according to the temperature profile. The impacts of geometrical and thermophysical characteristics on the temperature and stress distribution are evaluated using the analytical solution in the new disc. The comparison of displacement and stresses in the new FGM disc and old discs shows that the thermo-mechanical performance of the new proposed disc is improved significantly.

“…A variety of turbines, such as the radial flow [11], blade [12], and axial flow turbines [13], have been used as organic expanders in ORC systems. However, these expanders have been found to be inefficient due to significant flow losses and high operating speeds [14]. Additionally, due to the substantial pressure drop associated with fluid pumps, ORCs experience a large sealing performance challenge, resulting in the need for sophisticated design along with high manufacturing and maintenance costs [15].…”

Development of a Computational Fluid Dynamics (CFD) Numerical Approach of Thermoelectric Module for Power Generation

The recent innovations in thermoelectric generating materials have led to exceptional technologies that generate power from excess and lost heat. These technologies have proven to be of significant environmental and economic importance, especially with global warming issues and escalating fuel prices. This study developed a computational fluid dynamics (CFD) model for a thermoelectric generator (TEG) consisting of five TEG modules embedded between two aluminum blocks. The upper block collects solar energy and heats the hot side of the modules. The lower block has an internal M-shaped water channel to cool the cold side of the modules. The model predictions were compared with the authors’ previously published experimental results to assess its validity and reliability. A parametric study was conducted to investigate the effects of various solar collector block thicknesses and different water flow velocities on the TEG-generated voltage and efficiency. The results show excellent agreement between the model predictions and the experimental data. Moreover, the parametric study revealed a slight inverse relationship between the thickness of the solar-collecting mass, the efficiency of the system, and an increase in the heat flux. However, the relationship was proportional to the velocity of water flow.
