In this work, a novel approach to predict the fouling layer growth on internal surface of tube by means transient CFD model is presented. The takes into account complexity chemical and physical phenomena coupled with dynamic mesh. mesh method programmed user defined functions for allowing grow tube. study carried out through in 2-D computational domain which contemplates: radial effects profile...

Manufacturing a metal product with complex geometry usually will related to Investment Casting (IC) process as the process has the highest capability to deliver the intended objective. But producing the wax pattern for the process has already consumes half of the time of overall process. Rapid Prototyping (RP) is considered to be a solution as it capable to reduce the time in a large margin. Co...

A modified quadratic partial least squares (MQPLS) algorithm based on non-linear constrained programming is proposed, in which a sequential unconstrained minimisation technique is employed to calculate the outer input weights and the parameters of inner relationship. Other existing quadratic partial least squares (QPLS) algorithms are also reviewed and compared with the proposed MQPLS in the ap...

This work evaluated the process for heptaldehyde, undecylenic acid and methyl undecenoate production from castor oil, ester of oil ricinoleic acid. Experiments were performed in a continuous pilot-plant scale pyrolysis reactor. Those are very important green chemical products that might be obtained by thermal cracking oil. Transesterification produces ricinoleate its generates heptaldehyde. The...

Corrosion cracking of reinforced concrete caused by chloride salt is one of the main determinants of structure durability. Monitoring the entire process of concrete corrosion cracking is critical for assessing the remaining life of the structure and determining if maintenance is needed. Fiber Bragg Grating (FBG) sensing technology is extensively developed in photoelectric monitoring technology ...

The Joint Transportation Research Program serves as a vehicle for INDOT collaboration with higher education institutions and industry in Indiana to facilitate innovation that results in continuous improvement in the planning, design, construction , operation, management and economic efficiency of the Indiana transportation infrastructure. NOTICE The contents of this report reflect the views of ...

This work presents characterization data and viscosity of 34 secondary vacuum gas oils (H-Oil oils, visbreaker fluid catalytic cracking slurry oils) with aromatic content reaching up to 100 wt.%. Inter-criteria analysis was employed define the VGO characteristic parameters which have an effect on viscosity. Seven published empirical models predict were examined for their prediction ability. The...
