Al 7075 is a renowned high-strength engineering material used in automotive and aerospace applications, wherein many functional cylindrical parts are subjected to internal or external loads. Engineered parts with form errors (cylindricity CE and circularity error Ce) result in undesirable vibration and high deformation in rotating parts. In additio...

On the basis of the simulation results of premixed jet flame using liquid hydrocarbon fuel, an optimization method for the component of aviation kerosene surrogate fuels based on chemical reactor network (CRN) model is proposed. Firstly, computational fluid dynamics (CFD) numerical simulation is carried out for three hydrocarbon fuel jet flames of ...

In this research, a new optimum numerical method is introduced to analyze nonlinear conductive heat transfer problems. The governing equation and the boundary conditions are combined using the penalty method to define a proper cost function. Furthermore, a Moving Least Squares (MLS) approach is applied to approximate the derivatives in the introduc...

This paper focuses on the thermoelastic response of a non-simple solid cylinder with variable thermal conductivity due to a continuous line heat source. The solid is interspersed with a uniform magnetic field and magneto-thermoelastic interactions are studied under the purview of the dual-phase lag model. Laplace transform technique is utilized to ...

The effects of a cutout and thermal environment on the three-dimensional vibration characteristics of functionally graded cylindrical micropanels with different boundary conditions are investigated. The micropanel material properties are assumed temperature dependent and graded in the thickness direction. The motion equations are based on the modif...

At the mesoscopic scale, the milling deformation of complex components with micro-thin-walled features such as micro-channel cold plates and aerospace honeycomb materials is the main factor affecting their machining accuracy. In order to effectively control the deformation in the process of milling and improve the machining accuracy of micro-thin w...

Steel–concrete composite beams are commonly employed in civil constructions such as multi-storey building floors and long-span bridges. In case of significant span to depth ratios, excessive deflections and noticeable crack widths at the concrete slab may occur at the serviceability stage. In this context, internal or external pre-stressed tendons ...

The paper presents detailed modelling of rotor, electro-magnetic actuators, and accompanying electronics of an in-house-developed active magnetic bearing (AMB) test rig in a unified manner. The work is the extension of our previous work on a 1-degree-of-freedom (DOF) cantilever beam while in here, the challenging problem of levitating and spinning ...
