CFD Simulation of Abrasive Flow Machining Process for Additively Manufactured Parts

For the Abrasive Flow Machining (AFM) process, a highly viscous polymeric carrier mixed with the abrasive grain is used for deburring, edge rounding, and the general improvement of surface quality of workpieces with complex geometries. At present, time-consuming and expensive feasibility studies and parameter analyses are required for each new application. According to a market study of 2012, more than 50% of AFM users request the availability of a process simulation to model and optimize the flow and predict the results by the use of numerical methods. The key challenge is the accurate description of the complex behavior of the viscoelastic abrasive medium. Here, we examine a CFD approach to the flow simulation by integrating the non-Newtonian, shear-thinning characteristics of a Maxwell fluid into the inelastic Navier-Stokes equations. With the implementation of the viscoelastic material model in ANSYS CFX, physically reasonable results can be achieved and validated by experimental machining results of additively manufactured SLM workpieces. The results for flat, reference workpieces as well as for turbine blades are discussed and compared to experimental results.

Fundamentals of CFD with hands on experience

 This course introduces you to the fundamental theory of computational fluid dynamics with a basic hands on experience of the CFD tools. The course will kick start your CFD journey and will give you a flavor of all basic modalities of the CFD. The course is designed in such a way that a coherent linkage is established between a range of CFD concepts and practical learning. The course is divided into four modules. The first three modules are focused towards the theoretical understanding of the fundamentals of CFD. The last module is focused towards the practical hands-on experience of the CFD tools which familiarize the user with the CFD software.

Numerical modeling of condensation had been a challenging task for the researchers for many years due to its time scale and rapidity. Present work deals with the characterization of condensation in presence of non-condensable gases on isothermal surfaces which is a common situation in many condensing devices. The investigation includes the effect of different flow parameters on the condensation of the saturated steam-air mixture using a numerical approach. The study uses a wall condensation model through an ANSYS CFX solver. The effect of mass fraction of steam, operating pressure, and mass flow rate of mixture is studied. The investigation provides some key characteristics about film condensation which normally remain absent in condensation without non-condensable gas. The findings of this study will provide valuable insight into the thermal design process of components incorporating this phenomenon.

Get training on Introduction to Turbulence Modeling

 This course thoroughly introduces the turbulent flow simulations methods and turbulence modelling from the RANS and up to DNS. The course is divided into two parts, the first half covers basic theoretical and physical descriptions of turbulence. In the second half a wide range of turbulence models and simulation methods are presented and discussed. This course introduces students to closure methods for the Navier-Stokes equations as applied to turbulent and transitional flows. LES is increasingly becoming an established scientific computing approach for predicting transitional and turbulent flows. It is used extensively to elucidate the physics of turbulence and to compute flows of industrial relevance. Industrial and research problems are tackled well in this course, so that the students of different backgrounds will learn more about related domains.

Fluid-structure interactions are a crucial consideration in the design of many engineering systems, e.g. automobiles, aircraft, spacecraft, engines, and bridges. Failing to consider the effects of oscillatory interactions can be catastrophic, especially in structures comprising materials susceptible to fatigue.

NUMERICAL ANALYSIS OF HEAT TRANSFER FLOW IN VARIOUS TEXTURED TUBES

In the design of heat exchangers, where maximum research is focused on optimization, most of the efforts are much inclined to improve the heat transfer and effectiveness. In this regard, surface augmentation has been actively researched in recent decades. Usually, this sort of enhancement is dominant on the tube side. It has been seen that the study is greatly conducted in the past experimentally, but numerical studies are limited to determine friction factor or Nusselt number. Only a few discussed an important factor called entropy generation minimization. In this work, the analysis of groove tubes has been performed. The study anchors on the application of optimization techniques on the grooved tube design. After validation with experimental data, different pitch lengths other than the experimental study were examined. Later, the work is based on optimization using the Design of Experiment (DoE). Using this technique, the maximum thermal enhancement factor was determined as a function of the number of starts, the groove-depth, and the helical pitch length. It was found that the tube with a maximum number of starts and the least pitch length and maximum groove-depth gives the best thermal enhancement factor. Finally, the entropy minimization study as a function of Reynolds number was conducted on the optimized tube. The optimum Reynolds number is at the point where the tube has observed minimum generated entropy with respect to the smooth tube. Fig. 1 summarizes the whole concept in one picture.
