In this investigation, the structure of one-dimensional flame propagation in uniform cloud of volatile organic particles has been analyzed in which the structure of flame is divided into three zones. The first zone is preheat zone which is divided into three subzones itself. In first subzone (heating), particle cloud heated until the moisty particles reach to vapor vaporization temperature. In ...

A new analytical study performed to investigate the effect of the temperature difference between gas and particle in propagation of the spherical flames. The combustible system is containing uniformly distributed volatile fuel particles in an oxidizing gas (Air) mixture. The model includes evaporation of volatile matter of dust particles to known gaseous fuel (methane) and the single-stage reac...

At present, solar remote sensing instruments face problems regarding the short detection time for activity and need to preheat electronics before detection. The accurate orbit prediction function ensures that maximum error of payload system preheating is less than 8 s, enabling obtain stable reliable data, allowing adapt changes in limit position turntable rotation. To achieve complete by a orb...

The building energy consumption is an important part among the total society consumption, in which for air conditioning occupies almost 70%. of system fresh handling can be saved effectively when exhaust could recovered to preheat or precool air. Considering install locations requirements on field, pump-driven heat pipes (PHP) were developed as recovery ventilators (HRVs) and used existing expe...

This paper proposes data-analytics-based factory operation strategies for the quality enhancement of die casting. We first define four main problems casting that result in lower quality: [P1] gaps between input and output parameter values, [P2] occurrence preheat shots, [P3] lateness defect distinction, [P4] worker-experience-based tuning. To address these problems, we derived seven tasks shoul...

Premixed laminar flame speed determination is a crucial point since its values are used for the sizing of every combustion systems. In order to measure this parameter, an isochoric method can be used. It consists in measuring pressure (and possibly other parameters) spherical expanding flame. This allows get data large scope important pressures and temperatures supposing isentropic compression....

This article considers the design and control of 2-butene metathesis process. The process transforms a low-value feedstock derived from fluid catalytic cracking unit into more valuable products. economical optimization is applied to preheat–reaction separation sections, with objective minimizing total annual cost. dynamic response plant are evaluated for feed flow perturbations. Although system...
