Electric motor industries widely use cold-rolled non-oriented (CRNO) electrical steel sheets (ESSs) as the magnetic core. The sheets are of low carbon–silicon, thin (0.5 mm), and laminated and joined as a stack with gas tungsten arc (GTA) welding. A weld zone is affected by the welding heat and dependent on welding current (30–110 A). The fusion zo...

The fidelity of an advection-dominant numerical solution is significantly affected by the order of approximation applied for the given scalar. Numerical schemes that apply this approximation are generally prone to dissipative and dispersive errors while capturing sharp discontinuities in the scalar values. Hence, the present study introduces the Fr...

This paper presents a correlation analysis-based heuristic for the machine-part cell formation in the context of cellular manufacturing systems. Two new indices, viz. “mean correlation index” for forming the part families and “relevance index-modified” for identifying the appropriate machine cells are proposed. The machine-part cells formed by the ...

In order to analyze the effect of the double-spark plug ignition (DSI) on the heat release rate, cyclic variation in combustion and engine knocking, four different single- and double-spark plug ignition strategies are used for testing. Combustion diagnosis results show that when the DSI strategy is used, it can effectively promote the combustion pr...
