Abstract It is known that the Stirling numbers of second kind are related to normal ordering in Weyl algebra, while unsigned first shift algebra. Recently, Kim-Kim introduced a λ \lambda -analogue and r r -Stirling kind. In this article, we introduce algebra (called -shift algebra) investigate From derive ...
The q-classical polynomials are orthogonal polynomial sequences that are eigenfunctions of a second order q-differential operator of a certain type. We explicitly construct q-differential equations of arbitrary even order fulfilled by these polynomials, while giving explicit expressions for the integer composite powers of the aforementioned second order q-differential operator. The latter is ac...
The Stirling Cycle is one of the thermodynamic cycles that is close to Carnot cycle in term of theory, and these advantages cause to using Stirling engines in wide industries. The main objective of this research is experimental investigation of Stirling Gamma engine for refrigeration. In this investigation, effect of working fluid air and helium, operatring pressure of working fluid and dynamo ...
During the last decade extensive research has been made at Lund University, Sweden, on a lean premix (prevaporize) combustion concept with burnt gas recirculation and a metallic flame holder. From this concept a new lean premixed natural gas combustion chamber with internal combustion gas recirculation (CGR) has been developed for the V160/SOLO 161 Stirling engines. This combustor has ultra-low...
