“…The methodology, as presented in references [1] and [2], was originally developed for predicting the performance of a conventional engine. Liew et al [6][7][8][9][10] extended the methodology to predict a two-combustor engine's performance: they incorporated either the constants specific-heat (CSH) model or the modified specific-heat (MSH) model in the performance prediction of a two-combustor turbofan engine. However, Liew et al did not address the effect of the gas-properties model on the engine's performance.…”

“…However, Liew et al did not address the effect of the gas-properties model on the engine's performance. Nevertheless, the engine methodology described by Liew et al [6][7][8][9][10] is adopted in this study. In addition, the present authors have incorporated an 'improved specific-heat' (ISH) model in addition to the CSH and MSH models.…”

“…The 'target audiences' of this article are researchers who have embarked on the investigation of the engine's performance, in particular a novel engine concept (e.g. Liew et al [6][7][8][9][10]), without access to high-fidelity engine performance-prediction programs such as GasTurb, GSP, or TURBOMATCH. This article illustrates the importance of understanding the characteristics of the adopted gas-properties models that relate to the considered engine cycles in order to achieve reliable predictions for comparisons of performances.…”

Several gas-turbine-behaviour simulation programs have been developed so far to predict gas turbines performances under design and off-design conditions. The focus of the present investigation is on addressing the effects of the different approaches to modelling the gases’ thermodynamic properties on the performance prediction of gas turbines, in particular that of the conventional and two-combustor engines. Unfortunately, the use of various different models has resulted in variations in the predicted values for a gas turbine's performance under identical conditions. Also, in the comparison of the performance of the two-combustor engine with that of the conventional engine, the use of various different gas-properties models has shown different outcomes; for example, the predictions using the considered constant-specific-heat model have revealed that the two-combustor engine operates with a higher thermal efficiency compared with what is achievable using by the baseline (conventional) engine, whereas the predictions using the modified and improved specific-heat models have shown otherwise. Hence, depending on the applications, the selection of prediction methodology and its gas (thermodynamic) properties model might result in misleading findings.

At present, for the research of aero engine performance, it is necessary to calculate the overall thermal performance of the aero engine at the beginning of the research. For the mathematical model of the isentropic expansion (compression) process, most researchers use the ideal state value to calculate in the mathematical model, so that the calculated results have a certain error compared with the actual value. Therefore, the new isentropic expansion (compression) process mathematical model based on the Φ function is applied in this paper to the technical aero engine overall thermal performance calculation. After calculation and analysis, it is concluded that the calculation accuracy of the mathematical model provided in this paper is higher than that of the literature program for the overall thermodynamic performance parameters of the aero engine, whether it is the thrust of the aero engine, the unit fuel efficiency, or the thermal efficiency of the aero engine. It shows that it is feasible to revise and improve the mathematical model of isentropic compression and isentropic expansion process in this paper, more accurate calculation results can be obtained by using the new model in the performance analysis program, and more accurate numerical analysis can be carried out.
