  BOILING & CONDENSATION SECTION.  
 

CONDENSATION IN DROP AND FILM FORMS         
                        
To study heat transfer coefficients in dropwise & filmwise condensation, glass cylinder at the top of which two condensers hang and steam inlet at bottom, water is circulated through the condensers from common inlet.Transparent glass cylinder allows visualization of condensation process. Rotameter for water flow, Pressure gauge for steam pressure, temp. indicator for various temperatures.

TWO PHASE HEAT TRANSFER APPARATUS                                  
To study visualization of two phase of liquid viz. boiling & condensation. Liquid R-11 in which a hot cylinder is immersed. Boiling of liquid, observed over heater surface upto nucleate boiling phase. Condenser coil at the top of cylinder. Vapor is condensed to liquid. Measurements- pressure of vapor-pressure gauge, water flow-Rotameter, Control of heater surface temp.-Dimmer & Liquid temp.-thermometers.

CRITICAL HEAT FLUX APPARATUS                                              
To study of boiling heat transfer. A nichrome wire immersed in water and heated by passing current through it. input to nichrome wire, controlled by dimmer stat. Increasing wire input current increases & at critical heat flux the wire brakes. It is measured on meter. Magnifying glass and lamp to visualise natural connection and pool boiling and separate heater coil in water allows for various water temperature.

HEAT EXCHANGER SECTION 
Concentric Tube Heat Exchanger

CONCENTRIC TUBE HEAT EXCHANGER ( plain tube type )              
To determination of heat transfer rate, LMTD, heat transfer coefficient and effectiveness of heat exchanger. Unit consists of a copper tube inside a G I pipe, hot water from geyser flows through the inner tube and cold water flows through outer tubes. Hot water flows in one direction, cold water can be changed parallel or counter. temperature 
and flow rate of water measured.

CONCENTRIC TUBE HEAT EXCHANGER (finned tube type)             
To determination of heat exchanger, heat transfer coefficient, LMTD and effectiveness of the exchanger. Unit consists of a G I pipe, copper pipe with longitudinal fins over the periphery is fitted inside. Hot fluid is water obtained from geyser. Flows through the copper pipe. Cold fluid is air. flows over the fins. Direction of hot water is fixed, direction of air can be changed. Various measurement are provided.

CONCENTRIC TUBE HEAT EXCHANGER(plain & finned tube comparator type )
To compare the performance of finned tube with plain tube heat exchanger. two heat exchangers operating Operating in parallel and are concentric tube type. Inner tube carries hot fluid and cold luid flows outside. Hot fluid is water and obtained from heaters. 
Cold fluid is air supplied by blower to both exchangers. one exchanger with plain inner tube & other with finned tube.

10183
   
     
 
CROSS FLOW HEAT EXCHANGER ( air to air type )                        
To determine LMTD , heat transfer rate and effectiveness of heat exchanger.cross flow heat exchanger is air to air type.air flow supplied by blower. Hot air obtained passing air over a bank of finned tubes. Hot air flows through a tubes while cold air flows over the tubes at right angle to hot air.
