• CFD Letters received its first SJR (SCImago Journal Rank) in 2013. The journal is classified as Q3 in two subject categories: Fluid Flow and Transfer Processes | Modelling and Simulation. The 2y Cites per Doc metric (which is calculated using the same formula that Thomson Reuters' Impact Factor ™ uses is: 0.7.
  • Fluid flow and convective heat transfer over wall mounted cube have been studied numerically using Large Eddy Simulation. Surface of wall mounted cube and plane floor has a constant heat flux. Two subgrid scale models were used in this study; Wall-Adapting Eddy viscosity (WALE) and Dynamic Smagorinsky (DS).
  • The turbulent simulation of the droplet breakup shows the importance of the subgrid-scale turbulence modeling. One can clearly identify a stagnant low velocity zone in front of the droplet and a high velocity zone around the droplet. On the threshold between these two zones turbulence effects emerge resulting in the characteristic shape of the droplet during the breakup process at Weber numbers higher than 1000.
  • In the present paper, a numerical code has been developed with different turbulence models aiming at simulating turbulent bubbly flows in vertical circular pipes. The mass and momentum conservation equations are used to describe the motion of both phases (water/air).

About CFD Letters

Written by Administrator on .

Computational fluid dynamics (CFD) has become a distinct field of knowledge, scientific and engineering practice and business. In the last few decades, computational technologies have improved dramatically to enable personal computing of handling sophisticated CFD calculations with the modern processing and memory modules. In the present time, CFD represent an unrelenting research tool in aerodynamics, thermofluids, biomechanics, safety, ergonomics, and sport sciences. The interaction between the development of novel concepts and methodologies and the application driven demands is creating an accelerated production of research focuses and intents. In addition, the diversity of CFD related fields stimulates researchers to interact, in an interdisciplinary environment, in order to discover possible solutions for contemporary problems ranging from insect flight aerodynamics, through respiratory and artery flow dynamics to hypersonic propulsion and atmospheric metrology.

CFD Letters publishes as rapidly as possible manuscripts of high quality which addresses eminent topics of computational fluid dynamics theory and applications. Being an international, peer-reviewed, online and open access journal, CFD Letters presents a world-wide forum for the dissemination of knowledge among engineers, scientists and mathematicians working in the field of computational fluid mechanics.

The submission, review, and publication processes in CFD Letters are comprehensively web-based in order to facilitate the major goal of rapid publication. In addition to its distinguished fast publication time, CFD Letters is the first rapid publication journal devoted exclusively to computational fluid dynamics research.

Effect of Swirl in a Constant Speed DI Diesel Engine Using Computational Fluid Dynamics

In the current work, the operating characteristics of direct injection diesel engine is studied using Extended Coherent Flame Model for 3 zones (ECFM-3Z) model in a CFD tool named es-ICE, an expert system for internal combustion engines. The present study is validated with the experimental work performed by Colin et. al. 


Featured Editorial

CFD techniques were developed over the years with the hard way of trial and error, refine and many validation and assessment procedures. In the early 1973 the CFD group at Imperial College embarked on an ambitious and attractive program to predict simple shear flows, free and confined jet flows. The work was very intuitive…
