In this study, a novel plate methanol reactor (shell and plate) with a higher heat transfer rate compared to the conventional counterparts (shell and tube) was investigated. In fact, in the new configuration, all of the ...
The breakup model developed by Luo and Svendsen (1993)
implemented into CFD modelling of gas-liquid two-phase
flows assumes that the bubble shapes are spherical. The
simulation results usually yield an unreliable ...

Industrial tray air-dryers are increasingly used for the drying of agricultural products. The main drawback of these dryers is the non-uniform velocity distribution in the drying zone resulting in a non-uniform drying of ...
According to the growing energy demand in Turkey, Hydro Energy Research Laboratory (ETU Hydro) at TOBB University of Economics and Technology was established which is responsible for the Computational Fluid Dynamics (CFD) ...

This investigation compares the results from an experimental and
numerical study of air flow in a scaled-down underground coal mine model.
This was done in order to determine if numerical analysis can be relied
upon ...
Understanding the complex transient flow and heat transfer characteristics inside the furnace is a precondition to optimize furnace operation while maintaining high standard steel products. In the industrial furnaces often ...
In the present work, Computational Fluid Dynamics (CFD)
explosion simulations are performed in a large scale tunnel.
The length of the tunnel is approximately equal to one
kilometer. Three different cases of explosion ...
Manifold arrangements with bifurcations/trifurcations lead to head losses in a fluid system. It is necessary to predict the steady state head loss coefficients to characterise the losses arising due to these junctions. ...
The current work describes a multi-dimensional Computational Fluid Dynamics study of an in-house helium stabilized, laminar premixed flat flame, with an emphasis on the radiation modelling. The experimental work first deals ...

The liquid piston concept is suggested to improve the efficiency of compression and expansion steps in thermodynamic processes, due to near isothermal compression or expansion. Within the concept a liquid piston is utilized ...
An increasing number of companies and organisations have
started to outsource their data storage. Although the potential of
future investments in data centers is prosperous, sustainability is
an increasingly important ...
In traditional design and optimization of vehicle’s aerodynamic performance, there are few considering about engine compartment’s influence on vehicle's air resistance. In order to find out the engine compartment’s influence ...

Temporal data is common in real-world datasets. Analysis of such data, for example by means of clustering algorithms, can be difficult due to its dynamic behaviour. There are various types of changes that may occur to ...
Thermal management of densely packed chips is critical for developing prevailing chips. For years, conventional air-cooling techniques have been utilised for numerous microsystems where fans and heat sinks were used in ...
Jet impingement boiling has been studied extensively and has been identified as one of the most promising thermal management techniques for high heat flux applications. Unfortunately, only a few numerical studies have been ...
