ENERGY-EFFICIENT INLAND CARGO SHIP DESIGN BASED ON FUEL CONSUMPTION AND CO2 EMISSION CONTROL USING CFD

Journal of Naval Architecture and Marine Engineering, 2023
Inland ships usually face some additional restrictions in comparison to the sea-going ship. Apart from the regulations imposed by each country, the effect of restricted waterways governs the major ship design constraints. For this reason, designing energy-efficient inland ships incorporating shallow water effects is very challenging. There is little research done to overcome these challenges; most of them lack the comparison of improved design with the existing one. This paper has analysed1634 general cargo ships from existing Bangladeshi inland cargo ships' data and considered 281 ships only for performance evaluation after data verification. The selected cargo ships were further assessed by using revised Energy Efficiency Design Index (EEDI) parameters applicable for inland ships of Bangladesh. Fuel efficient and less CO2 emitter efficient cargo ships were identified. After considering the effect of shallow water, a set of ship design suggestions is proposed. These suggestions were validated by redesigning an existing cargo ship based on the suggestions and comparing their resistance with the parent hulls. Computational Fluid Dynamics (CFD) is used to calculate the ship resistances and it is found that 13%reduction in total resistance can be achieved simply by choosing improved principal particulars based on the proposed design suggestions.

NUMERICAL PREDICTION OF FREE SURFACE WATER WAVE FOR THE FLOW AROUND CAMBERED HYDROFOIL

Journal of Naval Architecture and Marine Engineering, 2023
In this study, the implicit Finite Volume Method (FVM) based on Reynolds-Averaged Navier-Stokes (RANS) equations are used to simulate the flow past a hydrofoil that is submerged in the vicinity of the free surface of water. To simulate the turbulent flow around the hydrofoil surface, realizable k-ε turbulence model is used. The Volume of Fluid (VOF) method is incorporated into the numerical simulation to capture the interface between water and air. The free surface wave generated by the stream around NACA 0012 hydrofoil is computed and compared with experimental results to validate the numerical simulation. Grid independency is checked by using three different grid sizes and the validation is done by comparing the experimental results of ratio of submergence level h/c=0.95. Finally, the cambered hydrofoil NACA 2412 is analyzed to predict the free surface water waves for seven submergence ratios, ranging from submergence level h/c= 0.95 to 5.5. The pressure coefficient, velocity contour, static pressure contour, and force coefficients are shown graphically and in tabular form for Froude number 0.57. The restricted and shallow water effects are also studied in this research. This study reveals that implicit finite volume method can predict the wave of free surface due to flow past cambered hydrofoil satisfactorily. J. Nav. Arch. Mar.

Reanalysis of the revised EEDI parameters for inland ships of Bangladesh

Proceedings of the Institution of Mechanical Engineers Part M Journal of Engineering for the Maritime Environment, 2023
A revision of the Energy Efficiency Design Index (EEDI) formulation was previously proposed to be useful for inland ships of Bangladesh. The study incorporated the shallow water effect using Schlichting’s method which has been developed in 1934 based on a large number of ship model tests to show how a ship’s resistance in shallow water deviates from that in deep water. However, the evaluation and presentation of Schlichting’s results did not cover all range of ship parameters. This reanalysis has considered the shallow water effect by actual measurement of 15 inland ships of Bangladesh. Later, the results of Schlichting’s method were compared with (a) actual investigation, (b) an improved version of Schlichting’s method proposed by Lackenby in 1963, and (c) a new method proposed by C B Barrass in 2004. It was found that the deviations of Schlichting’s results are much higher than Lackenby and Barrass’s methods in comparison to the investigated results. In a previous analysis of the inland ships of Bangladesh, the Maximum Continuous Rating (MCR) of the main engine was considered by using the Holtrop-Mennen method. As this method requires too much ship data, that analysis had assumed some unknown required ship data. This reanalysis has overcome that problem by the physical investigations of the same 15 inland ships of Bangladesh. The average MCR for inland cargo ships and oil tankers of Bangladesh are measured as 70% by the investigations, whereas it is 80% for passenger ships.
Mixed Convective Heat Transfer Analysis by Heatlines on a Lid-Driven Cavity Having Heated Wavy Wall Containing Tilted Square Obstacle

Mathematical Problems in Engineering, 2023
The current problem studies the mixed convective heat transport by heatlines in lid‐driven cavity having wavy heated walls with two diamond‐shaped obstacles. The left and right vertical walls are both cold, whereas the top wall is adiabatic, and the bottom wavy wall is heated. The relevant governing equation has been calculated through using the finite element method as well as the Galerkin weighted residual approach. The implications of the Reynolds number (10 ≤ Re ≤ 500), Richardson number (0.01 ≤ Ri ≤ 10), Hartman number (0 ≤ Ha ≤ 100), Prandtl number (0.015 ≤ Pr ≤ 10), Undulations number (1 ≤ N ≤ 4), and inner diamond shape obstacle are depicted by the streamlines, isotherms, and the heatlines. The convection heat transfer is observed to be fully developed at a high Prandtl number, whereas heat conduction happens at poor Pr. In particular, the undulations number has the greatest effect on the streamlines and isotherm contrast to a flat area. The Nusselt numbers increase as the Reynolds and Prandtl numbers rise as well. The isotherm, streamlines, heatlines, Nusselt number, and fluid flow are shown graphically for several relevant dimensionless parameters. The result demonstrates that a single oscillation of a heated wall with such a poor Richardson number is optimal heat transport in the cavity. The presence of undulations minimizes the cavity area; the case N = 3 makes quicker fluid motions and better heat transfer in the present research. Additionally, the interior obstacle size reduces the amount of space it takes up within the wavy cavity, and it was observed that the obstacle with diamond size D = 0.15 is better than that with any other size.
