• Optimisation of nursery rearing for megalopa of giant mud crab Scylla serrata (Forskal, 1775)

  Indian Journal of Fisheries · 2019-03-31 · 12 citations

  articleOpen access

  Three nursery rearing trials were conducted to overcome the inconsistent survival of megalopa of the giant mud crab Scylla serrata (Forskal, 1775) during metamorphosis to crab instar. In the first trial, 3-4 days old megalopa (4.73 mg mean body weight) were stocked in hapas erected in outdoor brackishwater ponds and indoor fiberglass (FRP) tanks at densities of 500 nos. m-2 and 1 no. l-1 respectively and reared for 15 days using minced clam meat (Meretrix casta) as feed. Outdoor hapas were provided with seaweed, Gracilaria tenuistipitata as shelter. Mean survival rate of crab instar following three consecutive runs were significantly higher (p<0.05) for megalopa reared in outdoor hapas (57.7±2.7%) over indoor FRP tanks (24.1±2.2%). To ascertain the life stage that yields optimal survival on weaning from indoor hatchery to ponds, zoea 5 (Z5) and megalopa 1-day old (M1), 2-day old (M2), 3-day old (M3) and 4-day old (M4) were reared in hapas for15 days and fed on minced clam meat. Three day and 4-day old megalopa demonstrated significantly higher survival rates (p<0.05) of 62.3±3.08% and 69.6±2.35% respectively to crab instar stage at conclusion of the trial. Megalopa (3-4 days old, 5.05 mg mean body weight) were stocked to 100 l tanks (stocking density - 1 no. 4 l-1) and reared for a period of 8 days using different feeds viz., artemia biomass (T1), minced clam meat (T2), crab larvae (T3) and artemia nauplii (T4) in the third trial to evaluate various production parameters. Crab instar conversion rate (number of crab instars/number of megalopa stocked × 100) was significantly higher (p<0.0001) for megalopa fed using artemia biomass (T1) and minced clam meat (T2) at 74.66±5.81% and 72.00±2.30% respectively. Results of the present study indicate that, high density rearing (500 no. m-2) of megalopa (3-4 days old) in outdoor hapas provided with seaweed refuge for short periods (15 days) would yield higher survival rate to crab stage. Nursery rearing of megalopa in ponds reduces the hatchery phase in mud crab larval rearing and maximise production of crab instars.

• Scale-Up of Shear Thinning Fluid Mixing in an Unbaffled Stirred Vessel with Eccentrically Located and Modified Impellers

  International Journal of Chemical Reactor Engineering · 2019-01-19 · 2 citations

  articleSenior author

  Abstract Mixing of a shear thinning fluid was scaled-up by maintaining equal Reynolds number (Re), tip speed, and power per volume. A standard 45° four-blade pitch blade turbine (PBT) and a modified version of the same impeller (DF-PBT) which provided simultaneous upward and downward flow were used. The impellers were located eccentrically, and the effects of scale-up were determined. The distribution of a tracer solution to evaluate mixing progress, power consumption, and flow fields were analyzed to compare the three different scale-up rules. The same endpoint of mixing was achieved in all cases of PBT with noticeable differences in flow profiles. Higher power consumption and less time were necessary to complete mixing with equal power per volume compared to that with equal Re and tip speed rules. For DF-PBT, only equal Re rule resulted in values similar to that obtained at the small scale. At a scale-up ratio of 2, the selection of scale-up rule should be based on the time and power requirements of the process. As the effects of scale-up on eccentrically located impellers do not differ significantly from those of concentrically located impellers, impellers which have complex dynamics such as DF-PBT require further studies to understand scale-up effects.

• Investigation of impeller modification and eccentricity for non-Newtonian fluid mixing in stirred vessels

  Chemical Engineering Communications · 2018-09-10 · 8 citations

  articleSenior author

  A shear thinning fluid (1% carboxymethyl cellulose) was used to investigate mixing under laminar flow conditions in an unbaffled vessel. The effects of impeller modification in addition to eccentricity were studied. Quantitative measurements such as percentage of uncovered area and coefficient of variance (CoV) of a tracer solution distributed inside the vessel were obtained using planar laser-induced fluorescence (PLIF) method. Increased eccentricity was found to be more effective than increasing rpm alone in reducing isolated mixing regions size (determined by the percentage of uncovered area). The dual-flow pitched blade turbine (DF-PBT), which was the modified version of a standard pitched blade turbine (PBT), was designed to provide both upward and downward flow at the same time to induce more chaotic flow. Though numerical analysis showed this type of flow generated, DF-PBT did not return lower values for the percentage of uncovered area and CoV than PBT did. Power consumption data were also compared between the two impeller types and eccentric locations. Further analyses focusing on the interactions between the impeller blades and fluid rheology is needed to improve laminar mixing in stirred vessels by impeller modification.

• Experimental Studies on Effect of Nano particle blended Biodiesel Combustion on Performance and Emission of CI Engine

  IOP Conference Series Materials Science and Engineering · 2018-06-01 · 7 citations

  articleOpen access1st authorCorresponding

  This article is concerned with the study of effect of addition of Carbon Nano Tube (CNT) on the physiochemical properties of Biodiesel and to investigate its effect on the performance and emission of a single cylinder direct injection CI engine. The fuel selected for the present study were Diesel, Biodiesel blends (B20), and CNT blended –biodiesel. The Biodiesel used is Honge Oil Methyl Ester (HOME). Biodiesel Blends were prepared by adding 80% Diesel and 20% Biodiesel by volume with the help of mechanical homogenizer. CNT blended Biodiesel contains 50 ppm of CNT in one liter of biodiesel blends. The experimental studies were carried out in a single cylinder 4 stroke direct injection CI engine connected to an eddy current dynamometer with computerized test rig facility to measure the performance and emission. The experimentations were carried at a constant speed of 1500 rpm and varying the load on the engine. The results shows that increase in the Brake thermal efficiency with the inclusion of CNT to Biodiesel. The brake thermal efficiency of CNT added Biodiesel fuels were 2.24% better as compared to that of Biodiesel without the addition of nano particle at full load calculation. Also the reformulated fuel (Inclusion of CNT's in the Biodiesel blends) shows considerable reduction in the pollutant emission.
