Energy, exergy and economic assessments of shell and tube condenser using hybrid nanofluid as coolant

A comprehensive, multidimensional, thermal-hydraulic model is developed for the analysis of shell-and-tube heat exchanges for liquid metal services. For the shellside fluid, the conservation equations of mass, momentum and energy for continuum fluids are modified using the concept of porosity, surface premeability and distributed resistance to account for the blockage effects due to the presence of heat transfer tubes, flow baffles/shrouds, the support plates, etc. On the tubeside, heat transfer tubes are connected in parallel between the inlet and outlet plenums, and tubeside flow distribution is calculated based on the plenum-to-plenum pressure difference being equal for all tubes. It is assumed that the fluid remains single-phased on the shell side and may undergo phase-change in the tube side, thereby simulating the conditions of Liquid Metal Fast Breeder Reaction (LMFBR) intermediate heat exchanges (IHX) and steam generators (SG). The analytical model predictions are compared with three sets of test data (one for IHX and two for SG) and favorable results are obtained, thus providing a limited validation of the model.

Influence of quaternary combinations of biodiesel/methanol/n-octanol/diethyl ether from waste cooking oil on combustion, emission, and stability aspects of a diesel engine

This paper of ours deals with the automotive radiators. We have shown a computational fluid dynamics (CFD) modelling simulation of mass flow rate of air passing through an automotive radiator. Modelling has been done in Solidworks and exported to ANSYS for CFD analysis. In our paper, the main implication that we have drawn is that the heat which is been transferred by a radiator is a function of the airflow at different air velocity. We undertook this experiment on a single radiator of constant geometry on the basis of some parameters like the material of the radiator and the vehicle’s speed. The thermal analysis is done for different velocities of air mixture passing through different tube materials such as aluminium and stainless steel. The numerical results were compared and results obtained served as a good database for the future investigations.
