IMPROVING THE HEAT REMOVAL RATE OF AN IC ENGINE USING NANO PARTICLE MIXED COOLANT
ABSTRACT:
Performance of an engine is greatly dependent on the cooling system of the engine. Addition of nanoparticle to coolant changes the physical and chemical properties of coolant. Hence latent heat and thermal conductivity is improved. Quantity of coolant required of heat removal rate is hence decreased. Improving the thermal efficiency of the engine leads to decrease in concentration of emissions in the exhaust. Nanoparticles improve the cooling rate when they are used along with coolant oil as base fluid in cooling systems. The rising demand for powerful and efficient engines call for the use of a coolant with better heat transfer characteristics.

KEYWORDS: Nanofluids, Automobile radiator, Heat transfer Enhancement, Thermal conductivity. …show more content…

It is a closed loop circuit consisting of manometer, flow meter, valves, pump, vibrator heater, reservoir, thermocouple and radiator. The manometer is used to gauge the pressure at the inlet and outlet of the radiator. 30% of the reservoir is filled with the base fluid. The total volume of the base fluid in the entire system is kept constant. The thermocouples used in the experimental setup are T type thermocouples. The radiators wall temperature is measured using these thermocouples. Flow meter is also included in the setup to measure and control the motion. Here a vibrator heater is used to replicate the heat emission of any automotive engine. A DC power supply is used to run the fan instead of a car battery. The pH values in reference to the nano fluid stability and change in thermal properties, have been checked, before and after the experiment. So to augment heat transfer for many applications low values of nano fluid pH is needed. Hence a single point calibration technique is used to calibrate the pH

    A hot plate was placed under the ring stand. 50 mL of 3.0 M NaOH in a 250 mL beaker and a stir bar was placed in the beaker. The beaker with NaOH was placed on the hot plate and 3.75 grams of NaAlO2*5H2O was placed in the beaker. The temperature probe was placed in the beaker with the solution, not touching the bottom of the beaker. The solution was heated and stirred till the solution dissolved.

  • Andrew Brassksma Some Lessons From The Assembly Line Thesis

    165 Words  | 1 Pages

    Nowadays few people realize the value of education. In Andrew Brassksma’s essay,” Some Lessons from the Assembly Line,” describes how a college student understands the value of an education by working as a full-time blue-collar worker during the summer time. Often times, there are people without a proper education who are forced to take unstable and low-paying jobs to support themselves or family. But, many people who have access to education do not realize the privilege it is and often times take it for granted. In Andrew Brassksma’s essay,” Some Lessons from the Assembly Line”, he puts himself on the same level as other blue-collar workers, and this is significance to the author's purpose because he can appreciate his own situation to the

    Ruby Cole Dr. Morris Modern World History 2/7/23 The innovation of the assembly line revolutionized the efficiency of mass production, radically changing the 19th century both industrially and socially. An assembly line is a sequence of workers or machines arranged to work along a moving belt. In the 1900’s Henry Ford gained inspiration from meat factories, with each worker or machine dealing with the cutting of a certain part of the animal meat. He then utilized this process in his own factory, eventually expanding across America, eventually internationally, creating a working middle class.

    \section{Facility Static and Dynamic Control}\label{Calibr} The facility calibration is the transfer function between the oscillating gauge pressure $P_C(t)$ in the chamber (described in ~\autoref{Sub31}) and the liquid flow rate $q(t)$ in the distributing channel, i.e. the test section. Due to practical difficulties in measuring $q(t)$ within the thin channel, and being the flow laminar, this transfer function was derived analytically and validated numerically as reported in ~\autoref{Sub32} and ~\autoref{Sub33}. \subsection{Pressure Chamber Response}\label{Sub31} Fig.\ref{fig:2a} shows three example of pressure signals $P_C(t)$, measured in the pneumatic chamber.

    My group members and I have been creating, the greatest, Rube Goldberg machine in our classroom! Our group and I have been researching about some possible ideas or objects we could use to build our Rube Goldberg machines. We figured out that we would use water bottles, dominoes, parts of a medium sized cardboard box, a marble moving set, marbles, confetti (to put inside the balloon to see when it pops), and tacks. We would put confetti inside the balloon for when the balloon pops, it will almost be like a big celebration! To pop the balloon we would use a few tacks and tape it onto the domino.

    This coil has an electrical resistor which resists the flow of electricity, which in effect converts electrical energy into heat as energy goes through the coil. Due to this, the heat energy produced by the resistor heats up the water within the kettle to boiling point. The heating element is controlled by a bimetallic thermostat, which contains a variable resistor inside it. Integrated at the bottom of the kettle, it consists of a disc of two different metals bonded tightly together, curved in a particular direction. As temperature inside the kettle rises, one metal expands faster than the other, set up in a manner

    I. Introduction This experiment uses calorimetry to measure the specific heat of a metal. Calorimetry is used to observe and measure heat flow between two substances. The heat flow is measured as it travels from a higher temperature to a lower one. Specific heat is an amount of heat required to raise the temperature of one gram of anything one degree Celsius. Specific heat is calculated using several equations using the base equation: q=mc∆T II.
