The efficiency and economical performance of sewer systems is an essential issue in urban drainage. The need for sewers to carry sediment has been recognized for many years. One of the main problems in designing sewerage systems is the sediment deposition. Sedimentation in sewers occurs regularly according to the alternating natural flow. The present study investigates the hydraulic characteris...

In this work, optimisation of a brushless direct current (BLDC) generator design was undertaken by carrying out an electromagnetic and computational fluid dynamic study. The studies were carried out for different loadingoverloading conditions and angular speeds, keeping in consideration the required electrical and thermal parameters, firstly for the initial design and then for optimised designs...

Synthetic jets have been an area of interest in the recent years with constantly increasing industrial demand. Application areas are widespread and a strong focus is put on boundary layer control as well as on mixing enhancement. A synthetic jet has been studied using physical experiments involving high-speed camera footage and smoke visualisation. Additionally, threedimensional transient numer...

Thermal performance of a solar water heater mainly depends on the thermal stratification. Thermal stratification in solar water tanks is essential for a better performance of energy storage systems where these tanks are integrated. In this research work, the performance of a solar water heater with a mantle heat exchanger is investigated experimentally. The heat exchanger is assessed for a rang...

Background: An economical and integrated high-throughput primary screening strategy was developed for high-aerobic microbe Monascus purpureus cultivation. A novel and effective mixture culture method was proposed and used to realize the whole mutant library being high-throughput screened after mutagenesis. Results: The good correlation of fermentation results between differing-scale cultivation...

Numerical simulations of magnetohydrodynamic (MHD) hypersonic flow over a cylinder are presented for axial- and transverse-oriented dipoles with different strengths. ANSYS CFX is used to carry out calculations for steady, laminar flows at a Mach number of 6.1, with a model for electrical conductivity as a function of temperature and pressure. The low magnetic Reynolds number (<<1) calculated ba...

Thermal sprayed surface coatings are extensively used for a wide range of industrial applications. In the plasma spray process used in thermal spraying, the temperature of substrate and conduction of heat along the thickness of ceramic oxide coatings (TCOC) play an important role in the bond strength and microstructure of the coatings, which decides its performance and quality. In this study, u...

This paper numerically investigates a 3D mesh independency study of a straight blade horizontal axis tidal turbine modelled using Computational Fluid Dynamics (CFD). The solution was produced by employing two turbulence models, the standard k-ε model and Shear Stress Transport (SST) in ANSYS CFX. Three parameters were investigated: mesh resolution, turbulence model, and power coefficient in the...

The presented article deals with the description of a numerical model of a corridor at a Central Interim Spent Fuel Storage Facility (hereinafter CISFSF). The model takes into account the effect of air flows on the temperature of stored waste. The computational model was implemented in the ANSYS/CFX programming environment in the form of a CFD task solution, which was compared with an approxima...

Article history: Received: 14.06.2016. Received in revised form: 01.12.2016. Accepted: 06.12.2016. Turbochargers have become widely applied to diesel vehicle engines. The mixed flow turbine type is suitable for systems where compact power sources are required with higher boost pressure. The sensitivity of the rotor to incidence effects and tendency of the flow to separate have given rise to con...
