Finite Element Analysis of Heat Exchanger Network     
Published by (IJSER)
Authors: Mahesh Kulkarni.  Published March 03, 2018

Basic principles of Finite Element Analysis, discretization and applying basic principles to get the elemental solution and then by summation of results complex problem is solved. Same approach is used in the study. Mathematical model for outlet temperature of heat exchanger based on effec-tiveness-NTU method is prepared. Network of heat exchangers is divided into number of elements i.e. exchangers. For outlet temperature of each exchanger, developed model is used and generate set of linear equations. Equations are solved using numerical techniques. Final results are compared with commercial software HTRI results and found within ±1% tolerance.

VESSEL STERN FEASIBILITY AND GRILLAGE DESIGN FOR FLOAT-OVER DECK LOADOUT OPERATION     
Published by (The Royal Institution of Naval Architects)
Authors: Saisushank Botu, Mahesh D. Kulkarni, Rudranath Banerjee.  Published December 11, 2015

An 8300 MT deck was to be transported and installed on an offshore platform located 60kms south of Mumbai coast. The entire structure was to be loaded out on to a vessel from jetty using skidding system. The profile of the vessel made the stern section attract very heavy stresses and vulnerable during transfer of the deck. To understand the stress pattern and determine the values, a finite element model simulating the whole operation was developed and analyzed. Since the obtained values were much above the allowable limits, grillage and outrigger arrangement was hence modified. The revised stresses were found within the permissible limits and made the vessel stern structurally adequate to perform the loadout operation.

Finite Element Analysis based SIF Calculation and Comparison with various approaches for SIF Calculation     
Published by (ASME PVP)
Authors: Mahesh Kulkarni, Vivek Dewangan.  Published 

Detailed FEA, PRG ASME work, B31.3 and WRC329 approaches for SIF calculation are studied in detail. It is found that B31.3 provide the SIF values for run pipe only and are high. PRG used NozzlePro program and provide formulation for SIF. Detailed FEA was done as per guidelines in TR-110996. SIF calculated by detailed FEA are in line with PRG approach. Detailed FEA gives least values of SIF in run pipe. SIF values in branch pipe by FEA are more than PRG approach. WRC329 gives the SIF values in branch pipe only for few cases. From the study, it is concluded that detailed FEA and PRG approaches are in line. B31.3 results high value of SIF in run pipe. If these SIF values are used, it will be overdesign. As B31.3 does not have parameter of branch size, SIF calculated by B31.3 can not be used for analysis. For optimal design of the piping system, detailed FEA approach or PRG approach will be used.
